LOVE the comp on #1 and the golden lighting is good but i don't see any catchlights in his eyes. It doesn't both me that much because I'm sure his eyes are near black anyway but some will mention that (i get it ALL the time so I'm working to look for those).
#2 is good but a little too centered (he's such a cutie)
Love #3 but not the action. See how yellow he looks on the left side? If you convert it to BW then run the sepia it would be nice but honstly, I think the color version would work best for this one.
