I think this is probably better than your Wolverine picture. I think it's because it's done more realistically. Of course, that's rarely something to care about in comic books. I just think you're a little more faithful to the character. I like how his foot is stretching out like that. You can even see some interesting things behind his back.
It looks like clouds are forming or something. The way he's literally setting fire to the ground is cool. It even looks like he could be on the Sun! That's what the yellow and red color looks to me. His face is quite stern too.
