The girl is a beauty.

About the rendering, donīt get me wrong, but... donīt appears a low orbit flight, since the background donīt give you the depth feeling. The shadow is to much dense too. Appears to be a "mini" nova in a flight next to the floor, not over atmosphere.

Maybe you must add the horizon to the view, just where the planet silhoutte encounters the space.
Hope this makes sense.
