Just some ideas:
1. Sleeves or some type of arm wrap to cover the skin some or bigger arms (
2. Top half looks like a t-shirt more than a vest/flight suit, maybe something w/a different color to break it up.
3. The white/green top and bottom maybe some green striping on the plates?
4. Helmet and the gaunts look pretty cool along with the chest plates, maybe the ab plate under that we chatted about or a sash.
5. Utility belt ( I have one w/a built in ammo carrier on it and holster
Just some quick thoughts:) It's coming along.
