/ic/ - Artwork/Critique

I agree that OCs are fine, but fantastic if you actually make content with them. I spent years dicking around and just making anime fanart, until I finally took a chance and switched over to generating mostly original comics. People like short standalone comics that are funny or cute. Even just drawing a super short goofy conversation between your OCs counts.

It all depends on what you want to do in art. Even if you just want to do concept art, you can feature the same characters in them and still be making a visual story.
