The diamond is the correct size, it's the armor spacing. I had to try to even out the armor to try to take up more space on the vest. If I bring the armor closer together, there is way too much vest showing. I am at a disadvantage to smaller guys because I have way more space to take up with the armor on the vest than shorter guys. I posted the pic to my WIP 501st thread. I don't think I need too much more to do to the suit, at least I hope.
