Here's a tutorial opportunity for someone
Last night I was trying to add a girl I know catching a football into a scene with some players diving toward a football. I wanted it to look like the players were diving at the girl. The lighting is all wrong though. The player's pictures were taken at night with stadium lighting while the girl had strong direct sunlight. How can I fix the lighting on the girl to be more realistic?
I've attatched the 3 pics. (players, girl, and kinda what I want it to look like with lighting changes)
Maybe someone can help get this looking right

Thanks
