That one is awesome. The face is well lit and the eyes are very mystic. I see you're getting better at postprocessing. Keep on practicing and you'll be the next Heida :).
I took a very similar photo of my son for some challenge. Didn't enter it though. I really love the black and white treatment and the look on the child's face is priceles. Love the background/surroundings. Focus is right on and this is just an amazing capture. Congrats. I could stare at him forever.
