*Edit* Hopefully this comment will be more helpful.
I like the fact that there's an expression on his face, and the color of the shirt works well. However, it looks as if this was taken outside (against a garage door?) I think if your going to take a photo outside, it may be better to make use of a more natural surrounding...i.e. trees, grass etc.
No light in his eyes to bring out a spark in the photo. Don;t care too much for the background or his arms being chopped randomly. Decent expression and exposure.
This is excellent- that background is absolutly perfect! My only nitpick is the shirt's dominance in the photo- but thats IMHO. Nice work otherwise- one of the better of the challenge.
