First one is too dark / too much shadow
2nd one has a shadow on himself that "hides" him and his left eye
3rd is better, but wouldn't it be nice if you could have picked him up and turned him into the sun to get rid of the shadow altogether? Sigh...
From a photography point of view, the second one is the best one. In the first one he isn't look at the cam and because of the angle it's not very showing off any of his facial features to the camera. As for the last one, again the angle doesn't really show off anything. The angle for the body doesn't work as you don't actually see much of him.
I would definitely choose the photo in the middle.
