That looks cold!
The little clipper ship, or what it is, kind of pulls the picture down a little, though, because it's so saturated, while surrounded by almost exclusively blues, including all hints of light. If you had made it totally desaturated, it would have integrated a bit better already, but simply less with some blueish bounce-light should be best, I think. Also...you could try to make a very tight rendering of it, not so blurry, because the rest almost suggests the possibility of very clear shapes showing up.
Other than that, it's really strong! Ride on!
