Dude I think this is pretty bad, you can do better. You're thinking geometrically, not artistically. A tube viewed so exactly from the side that it's edges are flat, with a couple flat rectangles slapped on is not interesting enough. I think if you spent more time on the design of the ship you would get a better result, instead of jumping right into implementation when you have no idea what you're going for.
Hahaha! Perhaps you could try something a bit bigger next time?
Great palette selection, but the thing is really dull by itself.
Good execution for what you were going for, but you aimed too low.
{ A like the colors! and the shade is pretty good.
But the shape meke it looks like a flying dildo! 
Yeah - I know. I really can do much better, I know it. I'm not proud of it.
Thanks for your comments.
