It's okay, not too bad really.
The simplicity works, but the image isn't that interesting
It mainly neutral, as it doesn't stand out.
Which, is good for some like a simple scrolling background, but it's not something that would tile neatly, which is making me assume it's just supposed to be a simple piece.
I suggest upping the contrast, or maybe make the starry sky brighter along with being a bit more of a focal point.
