that looks like a good start. mabye you could add a flip down visor, like the #33 rots clone commander or some type of bigger goggle for better vision and diplay read outs. mabey even a small flipdown optic for 1 eye, like the colonial marines had in aliens.
on color, well what color is you dropship? it may be cool if your pilots had the same scheme as your drop ship, like it was thier ship. you could even customize the ship to the pilots, like mabey have thier own team insignia on thier ship and thier armor, say thier shoulders or somthing. it would be like thier ship had been through grips of mission and made it back everytime so they are very protective of it. sorry i was rambling there for a minute, but you get the idea.
anyhow hope that is helpful!
can't wait to see more shot of your wip crew!
