I could totally do that if I remembered where I got them from. :c But unfortunately, I've gathered stuff from various sites. Quite a lot from deviantart. So I don't really have any link, per se. But I definitely plan to upload my resources sometime soon. When I do, I'll link you.
I'm a member of quite a few graphic forums. If I want criticism, I just post in those. Not really interested in joining another atm, sorry. Maybe sometime in future.
