Decrease the Sea level in Lunarcell for your planet, - that will get rid of the shinyness. Also, make sure you have a high complexity land with plenty of craters to make it look damaged. Increase the depth of the air (though this will affect colours, so you may have to fiddle with them a bit).
The nebula is also a little bright, and the engine glows too dim. Get rid of the white outline on the text, and possibly change to a more interesting font. Try to add a few more stars up the top as well.
Despite saying all that, I do like it - the camera's in a good spot, so my initial reaction was a good one. These things cropped up onyl after I'd been looking at it for awhile, and they're mostly settings changes - details that can be fixed relatively easily.
