Voted earlier, but coming back through to comment, and now bumping up. When I saw this the 1st couple of times, I saw the hand on the kiddie, never even noticed that the shadow was a hand. Brilliant!
The sun and it's light bursts between these two boys. Rays of the sun spread out and the boy's shadows fall upon the sidewalk along. The shadows - it is the shadows that hook and capture my attention! The one boy stretches his one hand between the two of them creating a reaching shadow hand on the ground. Love how that shadow hand is perfectly framed between the two boys shadows that stretch out to the opposite bottom corners of the photo. Excellent work with composing all the main subject to create an compelling and intriguing image! I could very easily see this as a cover of a book.
