100% faked. i dont care if you think you use photoshop now and then and think you know what you're talking about, it's faked. for one thing, the size of his body is clearly off. his left arm is shadowed while his back is not, which makes no sense. Also, there is no shadow of him on the water, or house, or ground.
the sun is coming in from the right, the shadow on his arm is supposed to be there, there isnt supposed to be on in the pool, which there isnt, and you cant see the roof of the house so how do you know if theres one there. i hope for this kids sake he didnt photoshop a pic of him on top of a house.
