With a name "Ship of Science", I kind of expected a toon-ish steampunk piece. Something that would not look weird beside a Victorian adventurer using "For Science" as a war-cry
My expectations aside, it doesn't look bad from a style point of view but I can't help noticing the large "turbine" at the front is covered by the hood. In other words, airflow would need to "suck" from the below at the front which, combined with the angle of the thrusters at the back, implies it spinning back over front when activated. I'd cut some air-flow holes in the hood or alter the turbine to be something else.
Then again, I'm one of those nutty people that likes his art looking sort of plausible (even when flying cars obviously are not)... so take my opinion with a grain of salt.
