Do I seem critique! I sure do!
You've a good control of form for a beginner! However:
1. The hands are WAY outta proportion! They are so tiny!
2. Your topology is way off. or your poly flow. When that model is
put to animation you'll get unwanted results. Particularly around
the elbows, knees, legs,shoulder, and mid section. The polys
should flow like real muscle and flesh.
The form is nice, it has a good shilloette. But your mesh design and flow will break your model when it comes to deformation.
Keep us posted.
