Ok, I guess for the first upload the shipis pretty good. Here are the stars.
As for the improvements:
Try to be more creative with the control panel. Just slapping some displays isn't very cool. Try using some other blocks creatively ;-) Say, two consoles and a forcefield between them make a pretty good holoscreen... That's just an example.
2) Those blue lights look somewhat out of place. I understand you're trying to imitate the engines, but actual engines look far better... Not to say some creative designs from the Engine Porn thread on forums (but those take a lot of space, which can be inapropriate for such a small build)
3) USD? I see you added a docker on the rear, but it is quite inconvenient to be used with a standard-issue USD dcking point.
4) A tiny detail, but if you rotate red cascades so they "pump" light rods into the main fuselage, this part will look even better
