The shadows on magicsteve do not correspond with the drop shadow beneath him - one is lit from the side, and one from above...If you also look at the other people in the background, you do not see such heavy shadows on one side of them, general ambient lighting is stronger.

You can try using the Dodge tool or Image>Adjustments>Selective Color>Blacks to try to bring it more into line with the rest of the image.

one way to do minimal change is to convert the pizza-guy to a signage instead, with white edges all-round (a cut-out look)
