Here are a few practice runs to get the angle right, and land this punch. Prisoner of the Mind issue 4 unleashed tomorrow on Comixology. Check it out.
I've got the basic angle done on this action shot. I was thinking about the jacket either moving left or right depending on how you punch. I thought it would go opposite of the action. I'll probably try it both ways.
And one final unrealistic kick pose. It would either knock your teeth out or put on stage as a dancer. It's fun to draw though.
