Awesome drawing! I love the colors and his expression. I think his hands look rather nice, which are always the hardest things to draw. His outfit is fantastic.
One thing I'd work on next time is watch where the knees are. The way the bandage is on there, it looks like his thigh is about half as short as it should be. His forearms might be a tad long as well.
I love the movement of the scarf, but maybe splitting two two ends and letting them flap a bit more separately would look better.
Keep up the good work!
