A few things:

- The text needs to be removed. It's placed sort of randomly and it completely breaks the balance of the wallpaper. So you either place it in a better way/differently so that the composition remains balanced, or you just remove it (I think removing it would be better).

- I am not sure about those two dark stripes at the sides. I generally think that in scenic and illustration type of wallpaper it's always the best thing to avoid to use pure black or pure white, because these colours don't even exist in nature (black and white are never that pure and are always, even if it's slightly, mixed/blended with other colours). The fact that you used such a pure black makes it think as if the image was suddenly truncated, while I am sure those two black stripes most likely are shadows, am I right? Shadows in nature are NEVER pure black. I suggest you to change the colour of these stripes to a very dark blue since the predominant colour, in this wallpaper, that influences the others is the blue.

Other than that, it's a crisp wallpaper, and if you fix these details I pointed out it could turn out to be an ever better wallpaper.

[Edit] I see that you corrected these things, and now it does indeed look much better. Good job!
