Sweet, man! It's super graphic... awesome shape language. It's like he's riding on the prow of a spiky boat made of Kryptonite. I like the first one a little more. The color dodge on the guy is a nice touch in the second one, but the additional smoke in the bottom right and the glowing trees might be messing with your value pattern a little too much. I just like how clear the separation between light and dark is in the first one, but you could probably push the focal point a bit more. Maybe hit him with a little dramatic lighting or something.
Great posty post Carl. love how epic it is.
I love both of them man!
