Thanks for your design!
My suggestions would be to make it less cartoonish and more dark comic. Also, we've updated the contest brief because we've had to change the name to Merlin's Stars. Due to licensing issues we'll need to de-emphasize any likeness to Einstein. Make it more merlin/wizard-esque. longer hair, maybe a goatee, you can add shoulders and hands with an active stance, but no more than a half body.
Hope this helps! Thanks!!
