I agree with Joe, the clothes are a bit big. But I must admit, you did a great job on the shading. My favorite part about this drawing is the way you drew his head/face and shading. Great job! Keep up the good work!!

Its not just you, I did the work and noticed that... kinda one thing that bugs me about it.
