We really like the fun approach to your Hero! And the color scheme is really, really great. The changes are right on point, as well.
I am not sure how this would evolve the concept... but we like the idea of the Hero representing diversity. Being from the US... representing diversity is important so it is appealing to all. Your hero is appealing to both men and women, but we need to make sure that we are appealing to all races too.
All in all... very nice work!
