Woowee, that purple mockup is busy! Recommend darkening the interior of all platforms.
Agree. When I first saw it, I thought it resembled a rave party more than anything. Probably all the flashy colored lights and insanely saturated colors.
The ship also lacks dimension, and the design just looks like something from an old sci-fi B-movie (as does the environment in the 2nd pic) or almost a parody of it; a simple geometric shape with various dials and knobs thrown in, some thrusters and panels for good measure. If you were going for darker, I think you may have missed it here. There's a lot of neat concept art of spaceships around the web you could use as reference, although there's probably a fairly wide skill gap, possibly design gap, between your work and theirs.
Doing an edit is going to be tough with all these NPA effects, but I'll try and see if I come up with something soon. Somehow.
