Just a small point. The engines look like jets. I always make it a point if I do spacecraft to not make any intakes on the engines. (Yes I know they do that in Star Wars) I guess I am just picky after having worked at fixing jets for about 14 years. It is up to you after all George Lucas saw fit to make the X wings with intakes. Just a tech point. the overall design is reminiciant of the discovery from 2001.

I cheated on my metaphysics exam by looking into the soul of the person next to me.
