Is the asteroid at the front a part of the background image or is it added in? It blends well.
The asteroid in the foreground is not part of the background image, and is, in fact, two halves of different asteroids that I had to fuse together to make one asteroid =P
The foreground asteroid was created by taking the left and right asteroids in this image, which are only partial asteroids (part of the asteroids are cut off by the edge of the picture), and cutting them out / combining them to make a single asteroid for the foreground: http://i28.tinypic.com/2yx3ul0.jpg
Hm, make them smaller I'd say and take away the blur I'd say. Since they're sort of banner-like it makes your eyes want to read across them, and thus since they're rather large, mine at least have trouble looking at them for extending periods of time. I'm not sure why, they just seem sort of... In your face, as it were.
