So, I did some research today and I was trying to find some different places to post (forums) that I'm looking for comic book artists... I've had 20-something artists email me so far, some that are good, but I'm fairly specific with what I've been looking for...
So, here we go!
CBR (Comic Book Resources)
ComicSpace (you end up doing a general post, not a forum)
ConceptArt.org (amazing artists on there)
I'll see if I can find more and I'm probably missing a few... No guarantees that artists will reply to your posting, though! Maybe I'll put some recommendations on how to filter out the riff-raff...
