Th position of his body really gives the drawing a dynamic feeling, and I think achieving that in a picture is quite a praisable success. Also, you have worked with the shades very well. It reminds me a little of american comics. In resume, congrats! =3
Cool work with the pose and the green highlighting. The green in there reminds me of the original game cover, with the green highlighting in the title. At least I remembered green highlights in the game's title.
This is really awesome. I love the green highlights you've added. It really pops in contrast to the darker, more saturated colors. The only thing I would point out is that the shading below the lips looks a bit odd (on the lighter side of his face). Other than that, this is spectacular colored. Awesome work.
