Very well done, I like the creativity.

"Stars" look like corn flakes, and wouldn't be visible in front of the clouds. Some white edges need cleaning up on the background spheres and the wreck in foreground. The jagged edges show you selected it with the magic wand tool...the pen tool or lasso tool will give you clean edges. The idea is good...with some tweaks it could be better.

Looks much better now...good luck!

Nice image

Don't forget to post the sources used

Thanks, I really didn't use any sources though, except for two textures that were just on my computer for a long time, not sure where I picked them up. I'll add those textures though to the source list. Hopefully my entry will be allowed.
