Maybe it's me seeing things where there's nothing, but:
These two pictures are so much better than they already are when you look at them side to side in this order. You can almost see them move from one pose to another.
I'm 90% sure it was Phil's idea, he's the one holding Steve's head, and who had to move more to go from picture a) to picture b).
Phil didn't tell us who his favorite girl is because he's taken by @make-me-your-animal and the magazine readers would be confused if he simply said "Jasper". <3
