Did you ever see that strange childrens tv show called "the tribe" ... The remind me of that!
He has the right face to be a kid out of "the tribe" too
2&3 are the better processed of them, the forth looks like it was taken in a photobooth... Quite effectively, if that was the intent...
3 is effective, although not my bag
2 is the better one, if a touch too washed out
What would 2 look like b&w with a little more detail in his nose and the stripe darker?
