Me, I won't watch the trailers for a variety of reasons. Just a personal thing.
Biceps are looking good, nice work
Suspenders are common so great idea there.
When you say glue pieces of armor together are you referring to the different plates, like joining the kidney and butt plate for example? If so I say no you definitely don't want to do that, first being you won't be able to get your armor 501st approved secondly you'll kill your mobility. Snaps and nylon webbing or elastic are very common. Hope this helps
