That is really nicely drawn! I would argue that the shadow may have been better directed somewhere to the left so hes kinda leaning over it. Mostly just to keep it in frame. This is still really cool though, it fits the character.
100% agree. It makes me double mad that I think DC may try to push this black Wally into other things since the Flash in the TV show coming out is Barry Allen but the actress playing Iris West is black -_- which would mostly mean Wally will be black in the new CW tv show.
