First off, nice work, looking good, just a couple of tweaks you could address.
Notice your left shoulder is sitting up more than the right, is should also sit over the bicep, not quite correct on the right either, just compare to the CRL image below, you may need to shorten those straps. Also the forearms need to rotate inwards, the cover strips should line up on the biceps and forearms.
You have one drop box being pushed backwards.
Slightly different gap at the top of the thighs, rotate the right thigh inwards.
Left shoulder strap on rear sitting under back plate, could be the issue with your shoulder sitting up high
Everything else looks pretty good to me, trying to get the correct look while wearing the costume is hard and does help if you have someone on had that knows the costume.
A couple of tweaks and you should be ok, good luck with approval.
