these questions are never easy to answer

“good enough?”

idk, it depends on you and your animation style and what you want from your character

is this what you wanted? an icey-blue demon guy? Then yes, it’s good
did you want a more “realistic” character? Then yeah, you can improve some areas (clothing, details on the limbs, face, etc)

here are two characters from “cartoons” (yes i called dbz a cartoon fight me)

completely different styles, but both are on TV, both are “good enough” in their own way
