First off, you got to learn how to adjust scan images when doing a wallpaper, cause as it stands now your character image is way too dark and desaturated to match the bright BG. As for the BG itself, you could do a lot more with it if you put some real effort and thought into it.

That, is totally cute. Stellar looks great in the middle, good thinking, good replacement, and good sense of romance. They're like the best group in Destiny and it's such a shame they died. You've really worked up the background, they're like mirrors and that's a nice use of colour, though the fact that Sting's head got a bit stretched is a shame and that it isnt your fault. Great work!
