Like Jr and DW, I hope you continue to work on this one. I don't think it would take much to turn this from a good start into a strong finish. Well done.
I think it is a little too dark. But the effects are good. One thing that would make this more realistic is if his left palm had a blue tint too it. You aren't going to put off that much energy and not illuminate the immediate surroundings.
I'd like to see this one finished too. It's off to a good start.
