There is no way in a single photo can any of us know anything about total shape and over all conditioning. It would have been better to show all top 3 girls in the front & rear relaxed pose.
Hard to hide any parts in those two poses.
The side chest pose is so twisted and turned. All we can say is Yes, she wins this pose. Now we have to judge 4 or 5 other poses.
I have also been at enough shows to know for a fact Center stage is great yet no guarantee
of first place. The head judge is not required to do that. In fact IMO I consider that leading the other 7 judges on the panel to place a certain way. I have seen head judges move who they think is the #1 to the far right. Others, might move who they think #1 is to center and then 2nd and 3rd. left and right of center. I have seen a group of 5 or 6 on stage and the head judge not move anyone. That forces the judges to judge and not follow.
Ok, after all that ramble the girl in the center looks great. At the level she is going for her glutes along with the rest of her must be in shape. No wiggle room there at all. Once the ladies or men turn towards the curtains BOOM we see glutes or butts.
All the best,
