mm, that's okay although the subject is rather depressing.
please don't be offended when i say that if you intend to continue drawing human figures, you need help. for starters, it's not bad, but it could get much, much better. the only advice i can give is practice, any time you can, with anyone who'll pose, with any photos you can get your hands on. practice drawing real people as much as you can- the observations that come with that is what'll make you better (it's what i did, for years on end, sometimes with a mirror for lack of anyone willing to stop.) tutorials and drawing step-by-step instruction books give handy hints and short-cuts, but those will give you nothing except boring poses and lifelessness.
so... yeah, practice makes better, so go for it, and show us some of the results!
and if you don't like me saying that sort of stuff then tell me and next time i'll shut up.
