uhm...it's confusing. You're trying to challenge our sense of depth, arent you? well...you're still creating depth...in quite a standar way I might add. If you want to make it confusing you should create completely opposite lightsources for each part of the ship....and I think stop working on this ship so much, draw some other ship shapes and try many ways to make all of the plains in the ship look like where they're not supposed to be.
Maybe look at Escher, and then look at cubism
