Lightbox Expo Challenge - Uniform Design Explorations

When I settled on the Space Army idea I began exploring some ideas for the uniform design. It wasn't an easy task to settle for one of them (God bless the Editors...), I needed something that could be adapted on different body shapes ed eventually personalized so to give some dept to the characters while keeping some design consistency.
When I finally decided, I went for some color exploration but the Red/black combination that I used for the starting designs felt still like the best one so I stuck with it.
