Not bad
Not a bad piece at all. Too bad the scanner mesed it up.
Your lineart is pretty good, though there are some parts tha look a bit off. Her hands for instance, dont really appear to ahve wrists. THen again, I always found it hard to review space art because of the anatomical differences.
The coloring is good, but a bit sharp. there's not much gradient and not much texture apart from the strokes. Shading is minimal, and you should've focused more on that, a gradient shading and some lighting.
The background looks good, brings the focus on the character but fills the void and makes it less empty.
