OK, don't kill me for because I know it's a crazy thought, but does this look Photoshopped to anyone else? The first thing I noticed was that the very top of Zeke's hair looks lit oddly. There's some white outline. Then I noticed that the shadow for Dak is in front of his feet so that he looks floating an inch or two off the ground.
I can't think of a reason to Photoshop it unless they wanted a cool "in focus" look for the guys up front... or to just put Zeke, Dak and Witt in front. Maybe they were running at different times and this is a composite of a few different laps.
I don't know why I notice these things. If it is a Photoshop job, it's pretty well done.
