@Bob-Crum I think this is really cool. I like how much you've put into the rendering and lighting.
It looks to me that the light on his face is running a little hot. I don't think it would get that much orange/yellow from the bomb. the eye whites would actually be the most orange/yellow.
From a form aspect, something about that left arm (his left) seems a little off to me. Also, his right leg looks a little off as well. Maybe thicken it up and turn it so the knee is facing the camera more? That's kind of a difficult angle but I don't know if the 90 degree angle is working as it is now.
From a character design aspect, I really like the character but I think his front body is a little stiff and boring compared to the rest of him. Could you maybe break up the overall shape a bit or give it more curve? Adding some functional costume designs would probably help too.
From a rendering aspect, you might want to lose some of the details in the darker areas--what is mainly hurting the image is all the "bumpy" design details on his skin, the lower character's googles and skin--it just gets to be "a bit much" and ends up overpowering the image a bit.
I can do a paintover if i'm not really communicating clearly here.
Like I said though, great style, great rendering and I love your use of color!!
