1)
FZDSCHOOL - you've never had a chance to attend any design lessons? Well, there's something for you! I've been watching these videos for a week now and they're really awesome. They don't teach how to draw, or how to use Photoshop, they're all about the rules - and that's the rules I've got problems with. Composition, perspective, colors - erverything you tried to guess on your own, explained by a professional in a funny and competent way.
2)
free textures for everyone!!!1! - free for personal and commercial use, no credit required! That's right, you can just download them and forget where they come from. That's a huge base of everything you've ever needed.
3)
Anatomy, oh, anatomy... - most of you probably heard about this site, but did you know about this thirty-second challenge? You get a pose to draw in thirty seconds (or any other time you declare), and then you get another pose, and another... Great thing for everyday training.
Good luck!
PS - the commissions are almost done! I'll post some pics of them when the sun comes out, eventually.
