I've got the perfect glow-up here, not just with the character (who ages 20+ years over the course of the story), but with my art style as well.
Early 1980's Carmen (I'm the kid in the pool. This image was actually created later than the next one in the list so it doesn't accurately show my drawing style progression):
Mid-late 1980's Carmen, flat colours, terrible backgrounds:
Mid 1990's Carmen, simple, rough image shading but still crappy background (I am wearing those extremely revealing shorts in the story for a reason):
Late 1990's Carmen, more refined image shading, much improved background:
Mid 20-teens Carmen, refined shading, detailed background (I am the tall one):
