It depends what you're going for. If you were trying to do a play on Creation, I don't think the green was right for the background. It makes the larger hand fade out and puts the stronger emphasis on the human one. Thus, I see it less as an interaction between the two entities, and more a focus on the human perspective. But, if that's what you're going for, I guess it works.
I agree that the lighting is very well done, though.
