Try www.dragoart.com, I learnt a lot of my drawing there ^^ And also, I use DA to find poses for my chibi dolls and others. I find this particularly useful :) And also, feel free to ask me if you want to know any more tutorials and things specifically, I'd be glad to give you some links! (But make sure to ping me, okay? As stated in my signature, I always forget >.>) Happy drawing, and cheers~
