* This is universally true for almost all fan works. When someone becomes a fan, their FanArt mainly starts out as something like simple OffModel blobs. The fan improves their art over time, possibly leading to their fan art being identical to the official art.
* ''FanFic/ASmallCrime'': The writer said that originally, Kit had long-ish blond hair (instead of short black hair), had blue eyes, and that she wore red armor (instead of wearing a grayish-black outfit), but then realized that she looked too much like Artie. The red armor was switched for a shirt to make Kit less impenetrable.[[spoiler: It was even said that Kit originally had red dragon-like wings]].
* ''Blog/AskHoopsAndDumbbell'': While the style remains heavily rough and sketchy, the artist's style has refined a lot in every other aspect over the blog's run.
* ''Fanfic/BloomingDreemurr'': The blog started out with simple images of the characters followed by text. Then colored images of the characters followed by text. Then text boxes with the characters faces. Then colored faces in the text boxes! Vee's been able to make moving images more recently, but they're too time-consuming for regular asks.
* ''Fanfic/BuggedRun'': This comic was started in part specifically as an art exercise, and it shows. The comic goes from flat black and white with no backgrounds, simple panel layout, rough linework, and deformed characters, to having full color, shading, detailed backgrounds, dynamic layouts, and more normalized character models by page 16.
* ''Manga/{{Evangelion 303}}'': After several years drawing, Grummancatís art has greatly improved. In 2013 he uploaded [[http://grummancat.deviantart.com/art/3-years-of-EVA-303-353829872 a pic]] that showed how much his style had changed.
* ''FanFic/TouhouM1GrandPrix'' -- The first 2 contests had different artists doing each skit, with one for the judging. From the 3rd contest and on, the entire competition was done by the same artist.
* The first season of ''WebVideo/YuGiOhTheAbridgedSeries'' had incredibly bad quality, audio, and acting. This actually has been [[LampshadeHanging lampshaded]] in several episodes.
* The design of the ''Webcomic/DiamondAndDazzle'' MLP fancomic changed quite a bit since its inception. Just compare the latest comic to the [[http://magerblutooth.deviantart.com/art/Diamond-and-Dazzle-Tower-454292413 first.]]
* ''FanFic/TintinAndAlphArtYvesRodier'' mostly experiences this due to being a completed work, instead of the rough draft that original author Creator/{{Herge}} left incomplete at the time of his death, though Rodier did clean up the artwork slightly after its initial release, along with adding colour.
