Great shot of the 'gator, but it would have looked much better on a surface than being held. Of course this may have been the only way you could get the shot, so maybe I'm being unfair.
though the hand provides a nice measure to tell how big the baby is, it really distracts from the shot, and the isolation of the gator might have made for a stronger composition. I like the focus on his face, though wish his whole body was more in focus.
