First, do a cleaner extraction on Ritsuka there~ I mean remove the lines around his body. Then, the wings are too stiff, and the colors don't really suit Ritsuka in my opinion. Try using colors from his hair, clothes etc so that everything blends better ^^ And you might try to lower the opacity of the wings too, to give it a more ethereal feeling. As for the sparkles...I don't know, the color seems odd somehow when compared to the background ^^ And make your signature smaller please *.* Ideally it should fit below the task bar.

The text looks very sophisticated, good job on that ;) We don't have enough Loveless wallpapers to satisfy all the fangirls out there I hope this one will eventually get into the gallery~

Yes you shud remove the glow from ritsuka.
and you shud change the bg.. it is not suiting.

but the wings wow. gread job me likey very much.
the butterfly and the blue light shades or wtv you call them are good..(well so far).
the bg just needs changing. it needs something soft and smooth..
not like what uve got right now which is kinda rought and completely out of place with the rest of the wp..
find your theme and stick 2 me.
