This is a very great piece of work - particularly on the founding members in this picture. It was a very interesting concpet putting Flash in the center of the group but it works for the style. Nice job
Excellent work! Looks really good!
I just found two mistakes:
1) Batmans eyes are transparent. They should be white.
2) The Martian Manhunter is blue. He should be green. I have a [link] for you, showing what I mean.
But apart from that, gorgeous! I think, I´ll have a look at the rest of the gallery.
