These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Art Evolution: Sadly averted. Wendy's artwork does become more detailed over time, but by the time she drew The Searcher And The Sword, her hand started to get wobbly. Discovery, the most recent comic in the series drawn by her, is just plain ugly. (A likely reason is the switch from traditional art to drawing digitally from scratch, including what people more familiar with digital art may see as an overuse of stock brushes and the like.)
Not so random. The not-terribly-fertile elves are trying to replenish their population by creating new pregnancies before some of them inevitably die in battle. Kahvi and Cutter say as much in their conversation following the orgy.
Canon Sue: Nightfall and Tyleet. Nightfall and Redlance's romance breaks just about all the established rules of the Elves' biology (They "choose" Recognition by telling each other their soul names, and when their conception is aided by a Healer, it doesn't result in the "flawed" product that the other Elves seem to think Pike represents), Nightfall is always written as being right in whatever stance she takes and seems to get undue attention from the cosmos in general. In a similar vein, Tyleet has her color-changing hair that predicts the coming of winter, her unfailing love for everyone, her ability to connect with humans and later learn their language, and the slice-of-life scenes of her childhood almost completely eclipse Venka's, even though they're about the same age and Venka's duties to the Wolfriders are much, much more important.
Evil Is Sexy: Winnowill. At one point in Discovery, Skywise dreamily reflects that for all the torture and Mind Rape she inflicted on the tribes, the lady had great tits.
Fan Disservice: Barry Blair's work in general. His interest in pedophilia themes in his erotic artwork tends to bleed into how he draws elves, and it's pretty obvious; if you're not into nubile, effeminate little boys in skimpy outfits, his tenure on the Wa RP staff is going to get uncomfortable very quickly.
Fetish Fuel Station Attendant: Where do we start. There's Strongbow: silent, brooding type, backstory suitable for woobiefying (lost his father at a young age, and his daughter was killed by people who put her skull on display), got mindraped despite being one of the series' strongest psychics, and otherwise traumatized. Clothes typically include thigh-high boots, a super-short "skirt" and open vest, latest iteration added a choker. Long hair, too. In one fairly recent comic (featuring him as the main character) he managed to get himself infected with rabies, the treatment for which involved being bound and gagged next to a fire, being forcibly injected with medicine, and barely decent full frontal nudity panels.
And in a particularly cruel twist of fate for the fandom, he's the comic's only remotely monogamous elf.
ElfQuest has dozens, if not hundreds of examples, depending on your personal taste - owing to a combination of Loads and Loads of Characters, Everyone Is Bi, and Polyamory as the standard form of relationships between the elves. To name a few: Winnowill (shapeshifting Big Bad seductress with Godiva Hair and a penchant for Mind Rape), Rahnee the She-Wolf (bloodthirsty 25% wolf, 75% elf chieftess with daddy issues who crawls around on all fours in very little clothing), Windkin (flying long-haired Bishounen adventurer with practically nothing on), Leetah (black red-haired dancer who is constantly said to have special magical healing powers)... the list goes on.
Germans Love David Hasselhoff: The series is huge in the Netherlands, and several conventions have been held (which, with it being such a small country, virtually never happens for one specific series). Likely because homosexuality, polyamory and sex in general are not considered very controversial in the country, and the comic barely merits a 10+ rating.
God Mode Stu: Rayek is a ruthless deconstruction of the trope, in that he has all the qualities of a God Mode Stu, but the story is told from his opponents' perspective. Which ends up making him the Designated Villain, no matter how pure his intentions are. When he finally gets a chance to tell his life story from his own perspective, he goes into full-on God Mode Stu narration, still seeing himself as the tribe's/world's saviour. It takes a long, long time before he turns into The Atoner.
Among his accomplishments: Discovering meat as a type of food, Training the Peaceful Villagers to eat wildlife before he's even reached puberty, providing them with horses and teaching them how to domesticate the animals, rescuing one of the ancient rock-shapers, learning how to fly, banging the chieftess of the next tribe he finds and fathering one of the world's most powerful magic users, becoming a soul vessel for dozens of elves, and finally, teleporting the elves' holy palace thousands of years into the future to Set Right What Once Went Wrong. He decides at the last second not to go through with it, finally realizing it would make him the villain. When he next uses his God Mode Stu powers, it's by using his already mostly forgotten soul vessel ability to seal the Big Bad inside his mind, dooming himself to live forever in agony as her jailer.
That, and Cutter basically cheated; he was ruled the winner because he supposedly didn't know the lodestone was "magic" (while it technically isn't, none of the elves had a concept for magnetic/meteoric iron and didn't have any other word for it than 'magic'), but he did know, and was actually the first person to be afraid of what magic might be in it. He just happened to forget; while it does make Rayek Unintentionally Sympathetic to some people, it also opens up an Alternate Character Interpretation for Cutter— did he really win the contest by accidentally cheating, or did he actually outwit Rayek with Obfuscating Stupidity?
The Scrappy: Scouter. Apparently few in the fandom would grieve if Dewshine and Tyleet just smothered him to death one night.
Seasonal Rot: The original quest is fondly regarded. "Siege of Blue Mountain" generally isn't. "Kings of the Broken Wheel". "Shards" and "Hidden Years" seemed to get back to the original quality a little, but Barry Blair's contribution after that left a lot of people feeling vaguely disturbed.
What Do You Mean, It's Not for Kids?: When issue 17 of the original series was published and featured an orgy scene with the Go-backs and Wolfriders before their big battle the Pinis got angry letters from parents complaining that kids read their series. You know, with the violence, death, horror and sexual overtones (especially when it comes to Recognition and the Abduction Is Love situation with Leetah) in the rest of the comic, it's perfectly kid-friendly. (Wendy pointed out that these same parents expressed far more outrage over the happy, affectionate, mutually satisfying sexuality in that issue than over the violence in it and later issues, including a panel in which Clearbrook is seen — in Wendy's phrase — "chopping a troll's face into hamburger".)
Ho Yay: Several canon male/male couples exist (Dart and Shu-Shen and later Dart and Kimo, Cutter and Skywise, Cutter and Redlance, Pike and Skot), and there's plenty of Ho Yay to go around otherwise. Particularly funny is a scene with Krim and Skot asking Strongbow, the only remotely monogamous and heterosexual elf in the entire series, to have sex with them.
And his response to the invitation is to just roll his eyes and go back to standing watch.
