It seems quite nice! There is a lot of parts about i that I like especially. The lighting is mainly good(although if he himself is emitting light, why does his back lack it?), and the posing is wonderful. It really seems as if he is launching himself using his left foot! The hair is well done, especially with the shading. As for the hand itself, I'd say it's very natural looking. It's shaped well, and there's a good attention to detail, while only relying on the basics to get a good sens if what he's doing. All in all, I think it's pretty excellent.
Another epic image, as far as poses go I myself am still perfecting that. But in a way your style kinda reminds me of mine a little, not that i'm saying i'm at your skill level just...yea. Epic image though, its great!
Not to bad, kind of Burning Gundam's Burning Finger from G fighter gundam combined with Super Saiyan from DBZ. Now that would be a great fight between my Herro and your Hiro, or even better an even more awesome crossover team up.
