Great, but a couple fixes. I LOVE space themed stuff. She is hot. But If it were my comission (I wish I had the art skills) I would make it look more high-tech. If she has a space ship (i'm assuming from the background) and all that technology, why would her window have a bunch of bullet holes in it?

In short-- Clean the glass, drop the reflection, except maybe her face, and add some data onto the glass, such as information about position in the galaxy, or local stars, tempature, O2 content, and current traveling speed.

-- That is what would get 5 stars out of me, but This is still GREAT art.

Your style just blows my mind :D
There are nice characters (gals :)),
the sci-fi, the mastered lighting, just epic backgrounds and the unique textures what you create/use.

this is amazing..i love the textures used. I just wish the background told more of story. I liked to know where this character is right now.
