Could you please add Venture Parts (with Impulse Engines) to the Nebula? That would be awesome.
The Galaxy-X needs some clean up. The Spinal Lance is slightly off center, its annoying. The 3rd Nacelle may be off center, I can't quite tell. IIRC, the Virgo Pattern on the Galaxy Style 3rd Nacelle isn't double sided, its a right side only. Could you tie the 3rd Nacelle to the Nacelle option instead of the Neck option?
