I don't think it's really abstract but I do know that it is really pretty. Nice use of effects all around, with the stars, planets, and flare thingies ^^ I think it really is so pretty that the black borders should of been excluded and the main image should of just been extended to the corners. A minor thing really but overall it's a great piece of work, great job!

Mm... nice background. That is what attracted me to look at this wallpaper. Not too busy, and not too dull at the same time. Just rightly done. You did quite well in terms of the extraction, but there are still some rough edges, especially in her hair. I am not liking the black bars in the top and bottom because it is just taking away the beauty of the wallpaper. It would be better if those were taken off. Other than that, nicely done! Keep them coming!

At first look, wow,.. it's stunning. Has nice colors, and some celestial background.
The details are abundant, from the cosmic clouds, to the sparkling stars. 'Beautiful' is the right word to describe it.
But on closer inspection, there are some things worth nitpicking ^_^'
-the extraction is off. There are jagged edges and missing outer lines, especially on her hair.
-the scan is a bit too blurry. But I don't know a good way to improve that other than reducing the blur effect.
-the planet is look-through. It's kinda weird. The stars behind it shouldn't be visible since the planet covers it.
-and I'm not sure about the abstract thing at the bottom part of the wall. The abstract stuff near the staff is fine, but I think as the distance grows, it should be less visible also to keep the wall being not too busy.

Well, apart from all the things I mentioned, it's a well thought concept, but could be much better executed. I really like the concept and the colors. :) I hope you have a time to improve the quality, if you do, then I'd certainly use this as my new desktop and add it to my favs right away.
