I did an edit:

Its a bit messy, but take a look at the hands, they might help you. Also look at the head. Although your piece has a more interesting
head, which you should try to keep, i think your head is too small. I think thats why the body was looking big. Lastly i hid the leg, becuase a guy wearing sandals and showing off leg didn't seem like a manly to me. The other stuff that was changed don't
worry about. For example i really like you collar and the jacket.
