For various reasons, humans may be illustrated realistically or in detail while wild animals appear cartoonish and/or unrealistic in a work of animated or illustrated fiction. The inversion of this is also not uncommon; where the humans appear cartoonish, while the wild animals appear realistic or detailed. Fictional creatures which are neither human nor wild (such as elves, intelligent human-like aliens) may be placed in either category for illustration style when appearing in a work that includes both humans and wildlife. This trope may also apply to works without humans if there is a similar animal to fill the same role.
The human audience will generally recognizes the appearance of humans than other (real world) animal species, which could explain both straight examples and inversions of this trope. If the wild animals look unrealistic, then most of the audience won't notice because they don't remember exactly what that species really looks like. The humans may also look more detailed to diversify their appearance. For inversions of this trope, this may be because it is easy for humans to recognize a character as a human even when the appearance is simplified, while they need to see more detail to know exactly what type of animal a character is.
No Cartoon Fish is a subtrope of this trope inverted, which is specific to fish being realistic and detailed. This is a Graphical Trope.

An American Tail: The humans are realistic, but the mice, cats, and other animals are cartoony.
Cinderella: The animals (the mice, the songbirds, the chickens, Bruno the dog, Major the horse, and Lucifer the cat) are cartoony but humans are semi-realistic or at least less cartoony than the animals. The four mice-turned-horses and other horses other than Major are semi-realistic though.
The Great Mouse Detective: The humans are realistic, but aside from the realistic horses, the animals (the mice, bat, rat, cat, dog, lizard, and octopus) are cartoony.
Ice Age; the original film only, as the sequels strangely didn't have humans. Although a few talking animals such as Manny had fairly realistic anatomy - Sid the sloth had strange eyes on the side of his head, as well as some other stylistic shapes on supporting characters. The adult humans looked fairly realistic, and the baby to a lesser extent.
Mulan: The humans are semi-realistic, while Cri Kee the cricket and Mushu the dragon are cartoony. Khan the horse is semi-real though.
DreamworksOver the Hedge has big-headed cartoonish animal protagonists. All of the humans are somewhat realistic, with accurate proportions.
Snow White and the Seven Dwarfs: Snow White, Prince Charming, the Queen (before and after transforming into a hag) and the Huntsman are realistic, while the animals are more cartoony, although still semi-realistic. The Dwarfs are appear as heavily cartoonized humans, the most cartoonish in the film.
The SpongeBob SquarePants Movie has cartoonish animated anthropomorphic sea-creatures. All humans (David Hasselhoff and the scuba diver/shopkeeper) are live action. The scenes outside of water have live-action backgrounds, and the sea creatures are live action when they dry and die.
This is done similarly in the series, but some of the rules are different. See example in Western Animation.
Jeff Smith's Bone graphic novel series has this in a simple zig-zag. The human-like Bone characters have the simplest appearance while the actual humans are quite realistic. The wild animals are somewhere intermediate; except the rat creatures - the antagonists, who are the most detailed (though not realistic).
In SpongeBob SquarePants, most of the characters are cartoonish animated anthropomorphic sea-creatures. Patchy the pirate, and his friends, are live action humans (and a mermaid)- save for his pet parrot, who is a puppet.
In an episode where Spongebob and Patrick go on land, they appear as live action puppets outside the water.
Mermaidman and Baracle Boy are the only cartoony humans in the show.
This is also done in the movie, with slightly different rules. See example in Film-Animation.
LEGO minifigures have simplistic shapes and unrealistic proportions (as well as all-yellow skinnote Except for sets licensed from media), probably to match the rectangular style of Lego pieces and models. The animal figures, however, have better curved shapes and more realistic proportions - probably so that humans will recognize their genus/species.
South Park: The humans are cartoony, but the animals in later seasons are realistic. Dogs and cats are still cartoony however.
Averted in the earlier seasons as both the humans and the animals were cartoony.
Inverted somewhat on The Simpsons. Except for those introduced early on the series (Blinky the fish, Snowball II, Santa's Little Helper), animal characters are depicted more realistically than the humans.
From the beginning the producers established a rule that animals would behave as they do in real life, although that rule has gotten a little looser in later seasons.
This trope applies to Stampy the elephant the most as he is actually semi-realistic, unlike most of the other animals and the humans.
Maus, a true Holocaust story - is an interesting (strange) example. All Jewish people appear as cartoonish, anthropomorphic mice - although this is just a metaphor, as they are humans in-universe. Other humans appear as other animals; such as Polish pigs, American dogs, and Nazi cats. In a panel in the first book, a real rat is seen running on the floor of a room that some Jews went into.
There was a ''comic within a comic'' in this book written by the protagonist, in which the characters are detailed and fairly-fairly realistic humans.
Five hats means that five tropers think it is ready to publish.
You are saying that you think this draft is ready to be published. That means the description is not ambiguous,
it doesn't duplicate an existing trope, there are at least three examples, and the title makes sense.
Is that what you meant to do?
You are saying this draft has a ready-to-publish hat it does not deserve and you are taking it back.
