This may be a little bit harsh, but I do like the peice.

Your proportions are off by a lot. Within a body part it will be accurate (say feet, arms, or face) but the proportions to everything else are wrong. Your head is way too large, as are your arms. The body is roughly 5 heads tall when it should be 7-8. The arms, while in proportion to the head, should reach midthigh and the elbow should bend at the waist. The torso and leg area are also too skinny.

It's a nice start though, I'd suggest to draw referencing a wooden maniquen to fix your proportions.
