You didn't precised a pose so I took the one from the image and moves the arm to make it look like he was throwing a punch.
(if you wanted a pose in particular or the one form the image it would have been good to say so.)
Anyway corrected:
Will this do
Sure, that works.
And the punch didn't really work. His body wasn't twisting to put more force behind it, and a hook is a power punch all the way.
