The lith-grain and the sunglasses make the kid look a lot tougher than in the original non-lith version. I like the tonality of his face which nicely offsets his dark, sillouette like hair.
If I can make a suggestion, I would burn in the right edge to match the dark left edge of the image. Looks more balanced, I think.
I usually don't intrude into other's visions but, in this case, I wonder how it would look if Mr. Cool was moved to the right by just 1 or 1.5 cm with the left side lightened while the right side is darkened. Just an idea. It stands on it's own as it is, for sure.
