...but I needed to use yet another seemingly pointless forum post to get critique on this. I'm really trying to better my art in the way of correct anatomy, so be RUTHLESS! ...but not too ruthless. :P

Here is a very good book.
"Dynamic Anatomy" by burne hogarth

I looked at the link of your drawing, and noted that it is anime. I believe if you want to be better at depicting the human anatomy, the best thing to do would be to do several study sketches of realistic human form, and after you have practiced that, what you learn will translate naturally into whatever type of drawing you favor.

It's that Full Metal Alchemist character who's missing an arm, right? Well, his left arm seems a bit too short now given the angle of the wrist. His neck is a bit odd too, as it seems like it should be more to the right. Other than that it's hard to say since you aren't dealing with realistic proportions in an anime character.

edit: Ditto to what DBA said.

Actually, no, it's not the FMA guy. I'll look for some good pictures of realistic anatomy to try. And, how can I make the angle of the hand more convincable? I stink at perspective, but even after practicing over and over, it doesn't seem to help.

OK...add me and i'll fix this for you...but you gotta do the rest :)

Dun want anybody to fix it FOR me. I just need a little word-guidance.

i won't do much, just want to fix something cuz it's hard to explain, i'll put it on a seperate layer so if you don't like it you can change it..
