Wow, this piece just seems to flow so nicely! I especially like the fact that you distorted the stars instead of keeping them straight and pointy, it looks like they're floating around the couple. It's a real treat to see so many pastel colors together, and the texture in the background prevents it from looking too empty.
The only thing I don't really like is the fact that some parts of the outline appear jagged - particularly, near the girl's jaw and arms. Probably from the outlines being too thin? You can cover this up by duplicating the outline layer and blurring it slightly, or making the outlines a bit thicker. But since I have a much smaller resolution than 2560x1440, it's not noticeable on my desktop.
Regardless, I know what my current wallpaper is :3
