Unknown world

This is my first space art. I was really worried about art during all this work, so I hope you will like it. First i wanna to make a spaceship in the coner, but after i decided no to do this.
I was dreaming to do something like this, and today I suddenly decided "Why not?"
3-4 hours of drawing
Adobe Photoshop cs6 (also my first work in cs6, before I was making art in cs5 and SAI)

I hope you like it! :3
