Everything's looking good except the under suit needs to be like a spandex material. Search for compression gear or under armor , although I don't prefer the name brand because their logos show everywhere and have to be covered. It is ok to have a separate top and bottom. Some troopers even use dive suits. But the cloth suit you have there won't get approved.
You might also need to put some actual buttons on the ab plate. I'm not 100% sure on that though. The TK buttons that you can buy from various suppliers are too small to cover those. You can find snaps with gloss black that will work. You wouldn't need to actually clamp them, just drill a smaller hole and push the top glossy piece in. You might need to get these anyway as it looks like you'll need them for the 3 buttons on the belt front. Refer to the Elite Nova Trooper CRL here http://forum.501stsp...ovatrooper-crl/ .
Just some pointers so you don't get held up when you submit it for approval.
