Wonderful
It is a beautiful drawing, I love the colors and I like the design of the space suit.
The only problem to me is, that the character doesn't really stand out from the background. Especially in the small view. If you squint at the pic (or you can try to blur it with an art program) she kinda gets lost in the background and the only thing that really stands out is the visor of her helmet.
I think that is due to the fact that you applied a proper highlight to the helmet. If you added shades and highlights to the rest of the body too it would really "pop out".
I think you did an awesome job on the background. At first sight, I thought you used water colors.
I also like the contrast of the flowing dynamic nebulas versus her rigid pose.
The hand looks like it could be wrong anatomically, but then again it could be the armor that is built that way.
I am not a fan of the white at the bottom, because it doesn't actually look like ground.
The title was a good choice to go along with the pic and a good play on words for this case.
Overall a great piece with wonderful colors and a nice idea, of course.
