Juxtaposition is a powerful tool, especially in photography. It lets you make commentary on an otherwise silent picture.
Pablo.raw must have either waited for a bit in front of the Studio Theater, or was lucky enough to have a flip-flop wearing, iPhone toting guy walk by as he got on the scene. The yelling mouth certainly screams “can you hear me now?” from the old Verizon commercials.
Whether he needed to hang around or not, it pays to keep an eye out on your surroundings and know when that makes the picture.
