yours are cool cid although you probably need to study anatomy a bit more, I'm shit at actually drawing people on paper, I need a photo for a base pose then add/change bits depending on how I want the drawing to look, I just stole some books off of my ex, dynamic anatomy, anatomy for the artist, and a couple of other books on the drawings of Luis Royo which are really quite cool, you should check him out.
I've got photoshop cs if you want it, I could get garf to burn a disk for you if I ask niceley.
