I was relatively satisfied with my Halo: Reach ODST, until I actually looked at a direct screenshot of one of the ODSTs ingame. I decided that I might as will try to make it look like it should, and this is how it turned out. The shoulder pads came from The Rookie, and the gauntlets came from a Reach Spartan. After doing all of the basic work, I hair-dried his neck brace, then stretched it down to the chest/back as well as I could, gluing it while it was still pliable.
