I like the colours, they seem to compliment each other very well. And I like that, I also like how the light falls on the asteroids. I'm guessing that they where made by some 3D program. Alao I have noticed that you have done the stars all the same, becuase I have noticed that some people have done some starts that I light tilted then others. That wouldn't happen becuase the light reaches you the same way as each other, so there would be no need for the starts spikes to be tittled.
