Well, for drawing anime, AnimeOutline is a good start. The only drawback with it is that it is very standard and doesn't really show you how to develop your own style. That said, it's really good for learning to draw. Another website is DrawingRef. It's got references of all sorts and a couple of tutorials here and there. It doesn't have many references, but the ones it does have are really good. Some are anime, some are semi, a couple is chibi, some are cartoon, some are realistic.
