It is in some regards though, if I don't make my work seen by people, I can't expect people to like/comment/etc if they don't even know I exist. Its a bit of both though for sure.
Also you can't really hate on anime in general. When something gets super popular, it breeds a lot of people doing it badly, thats just nature. Personally I see the same in concept art. There's a lot bad stuff out there. And they're are other forums which are less so. CGHub.com is certainly less anime/manga filled.
In the end, a lot people have differing tastes right. Just gotta find somewhere that matches yours.
Anyways, You've inspired to put up all my more recent work and get this shit in shape. So thanks for that (check back soon for a hole dump of work!).
Also keep that passion up, its what will make you great and wanna succeed. Just don't get bogged down in hating yo!
