Awesome job- great looking build! Just a couple of things I saw; is the neckseal riding too high up your neck? In the close up, you cannot see the ridges, really only the cloth underneath. Could be wrong though and it's just the lighting.
Also the chest piece could maybe be trimmed a bit, where it curves around and is pointing towards the back. It looks pretty close to the back piece where there should be a bigger gap.
Congrats!!
