Woohoo! I love seeing ATA Centurion submissions as an ATA wearer myself! Ultimately the DOs have the official say, but you've done a great job pulling your shoulder bells in since your EI app, and you've also successfully minimized the gaps on the rear of your leg pieces through your implementation of mobility cuts! Jus a couple other observations: You'll likely still need to pull your belt up a bit so that the plastic is closer to the bottom ab button, and your ab-kidney seam may also need to be addressed. The 1/4 white elastic on your shoulder bridges also needs to be shifted back to the rear, so that it's positioned atop the backplate armor.
It also appears that your chest plate also rides up over the ab piece in a couple of your poses (something I too dealt with), so you may consider tightening/shortening the strapping holding those two parts together. I see your straps are currently on the outer edges, so you could consider adding a shorter one in the middle.
Looking great, trooper! I look forward to seeing you in the L3 ranks soon!
