Mind you he's only two in this shot so I can't say what he was thinking but there's a certain maturity about his posture on that wall that's kept me coming back to this one. I can picture the expression that was probably on his face from just the profile.... In color there was nothing here, but the move to monochrome with a sepia tint seemed to draw the mood right out of the moment.
