Straightening this out would help a lot. Also, cropping in on just the boy and the dog would help composition as the other people in the restaurant keep drawing my eye away from your main subjects.
I have to wonder what this would look like in black and white. I have a feeling it would look like he was reaching out from another world. Great capture.
Nice capture - Great find - Think this could have been a much stronger image if a little better PP had taken place - Cropping and rotating the image to level the fence would be a big help and turning it to Black and white I think would have really made this image stronger - Our eyes keep going to all the reds in the shot like the table cloth and coors sign which competes too much with the real interest - The dog. Still a great candid street shot.
