Lighting looks pretty good in the back but his face needs some more fill. Try using a silver reflector or ring flash to get some light in the eyes. I'm guessing the background lights were added in? I dig they layout but dont think I've ever seen a stadium with that lay out of lights so this could throw off the folks who see it in the running industry. other than that cool shot!
The lighting was intentionally that way on his face but I definitely see your point that a hair more fill wouldn't hurt. There was a bit of fill coming from bottom right, you can see the octabox in the behind the scenes shot
Robin, the stadium lights are taken from other photos I took at that same stadium and added in post. They definitely add a lot to the photo vs the one without.
I just looked at this on someone elses monitor and I think the contrast on my monitor might be a tad out of whack. The photo is meant to be much less contrasty than it appeared on that monitor at least. I guess I shouldn't ignore those Spyder calibration reminders for so long
Thanks guys, I'll definitely consider switching up the background lights a bit more. Right now this is for him and Nike may be using some but these will be going on his website and in his press kit.
