Terry, please quit being an idiot. While your color comment is of dubious utility, your statement on hull shape was entirely useless because you failed to provide suggestions for how to make it better
Snopel! Nice to see you remained.
The only things
I don't like about it are the middle of the back-end, the overly-detailed weapons (possibly just me though), and the off-center nature of the main gun.
Image posted for clarification:

Particularly offensive to me are the parts circled in Green. The rear circle could benefit by removing the two center sections and replacing them with a single part, layered above the remaining two. (q and a keys while a part is selected, make sure CAPSLOCK is off)
The green circles in front are likely best handled by changing one of the two parts for a different section entirely. Experiment untill you find something you like.
The Gold/Brown circle can be corrected by adjusting the large gun's position down a few pixels. you may end up needing a half pixel, that's done with the Y Position text field under the EDIT tab while the part is selected. Add .50 to get a half-pixel. Re-adjust to fit.
You may allso want to beef up the area. Try adding a few pieces to extend the hull out to the red sections on the wings.
The Blue circle just looks barren, perhaps a third engine, or some other protrusion? This could allso be worked into improving the rear Green circle.
This time, please don't remove your ships from your posts. And try not to make another thread/topic for your ships, one is usually more than enough. (Certain exceptions do exist, and generally deal with Multiple Fleets/Styles, or an absurdly large number of ships)
EDIT 1: Clarity on Terry's failure.
