I created these outlines on Friday. Back when I made them I planned to do more after returning home from working late at the university however when I sat down to work I think I had gotten myself to work late enough. The difference between 1 and 2 are why despite the appeal of a flowing red cape, everyone lacks them. The addition of a cloak just obliterates the detail of a character's form. It can also make poses much harder to discern.
I myself am drawn to 4, 10, 9 and 12. Though I do also like what I made 12 do with his hands. I think it gives him a mystic quirkiness. 10 might be the weakest design of these selected though. He seems a little too "generic soldier hero" like.
