It is nicely done, but you should consider resizing it. It is much too large.
Scale in CIV is not exact, but it should be relative. There are quite a few other CIV Starwars fighters. Did you try to scale it off those? I have scaled mine off the firaxis jet fighter and each other.
I think the color is ok. I think it is dark, but 'ok'. The civ color on the wings is well.
For future consideration only, I recall that the wings and the center rotated independent of each other. I don't know if your model allows for that.
The only thing I think needs fixing is the size. I made this same mistake on my first version of the Hummer Avenger, and remade it to fix it.
