It's such a hard decision but here it goes:
3rd place: Dominicaninja "Ion Phalanx". Like the shading style and the ship's original shape.
2nd place: Pointguard "Small Stealth Fighter". I like it
1st place: Slight "Devourer Class Heavy Fighter". Just a piece of art. (I liked all of Slight's ships but it would have been unfair to vote only for them)
And.. honourable mention: TheHumanChimp "USB". Very good use of shadows and the most original of all lol.
