there are 6 rotating submodels on the mesh
1 in each engine, 2 crystals were the beams are, and the 2 rings on the shieldgenerators
the general shape of the vessel is almost a square from above, so that gives it a not-all-out vasudan shape i think
as for colors, i think the thing is that with red blue and yellow you have the full color palette covered, and that just makes the whole ship scream COLORS!!!! RAINBOW!!!
and combined with the strong glows that give the thing a kind of comical look, but somehow i like it that way *shrug*
my inspiration has not been star trek, you'd never guess it, believe me
