Hot. I would have liked to see more accessibility to the cockpit (I guess they have to climb over the seats?) and a more separate living area...but, all in all, a heck of a ship. Unique and inventive. I like the realistic weapon capability, i.e. not overloading it.
I don't know whether to like the Navy ship like thingy you got going here, or not... Anyhow, great detail, both inside and outside! Those engines have a whoosh-factor to be reckoned with, the magrail turret is an original design, and is that the outer door of the airlock right before the torpedoes? (Better hope they are not primed to explode on impact, heheh...). But as for the main cannon and the overall hull shape, they seem somehow less-inspired... But what the... I'm in a chemically-induced-but-otherwise-very-real good mood, so here's 5 smileys for you. Now throw it in the tub to see if it floats!
