I drew several thumbnail sketches for this one; more than you see here. One approach was from a closer angle and almost worked but it didn't show the characters clearly enough. In the context of a story you could show one of the fighters from behind or the back of his head, but for a cover we probably should see both of their faces and as much of their clothing/costumes as possible so they can be identified at a glance.
