I like the image a lot, especially the large rock formations (Can you explain how to create those?) I am still learning about all the different nodes & shaders.
I agree the ship is a bit of a distraction, but I think the placement of the ship smack dab in the middle of the composition is the thing that most people are being put off by. I would place the ship in a more dramatic position and angle, for example try a composition with the ship coming into the frame from the upper Left (In the bright Spot of the image).
Great work!
