I see you've stuck to the same seam lines as the actual costumes, excellent! Were you planning to make the concealed zips slightly visible (as per the constraints of a TV series) or make them truly "invisible"?
They'll be truly invisible, for now anyway. Until I get to be a master at this sculpting program, intense details will have to wait ; )
I'd like to finish up the uniform (with all its color and rank variations) and model a head and hands to go with it, just so I can start to plop this guy into my render screenshots.
