Glad you had the courage to post. It looks like you've already got an eye for seeing, now you just have to know WHAT you're seeing. Your proportions seem pretty good, but the structure isn't there. I can't get a good sense of the bone structure (which is usually very useful for the face if not the rest of the body). Also, the strap of the scabbard doesn'y seem to fall over the body like it should. The eyes are beautiful. That's an important thing to get in any drawing, and you've got a good start in that respect. I'd recommend going and investing in an anatomy book of some sort. You can get them at Amazon.com or Barnes and Noble's website.
Good luck, keep drawing, and post MORE!!!!
