Quarantaine. ;-; Any suggestions so that it can be submitted? Thanksss. 8d

I think you shouldn't put that traslucid version of her in the background, for starters. I think it's even written somewhere that you can't do that X)
Her glove is kinda grainy too...but it looks like a velvet effect, did you do it on purpouse? But now that I look carefully, there's grainyness in the smoke too, so try to fix that.
Also, the text seems chopped. I dunno, I just don't like it.
Hope that helps =)

like Astrologica said, it was deleted because of 'ghosting', which is basically the transparent, blown-up, version of Yuuko stuck in the background. Also, for the bg, it seems that you've use some filters. I'd also take out that filter in front of Yuuko as well (it's distracting and unneccessary). You're extraction looks good though.

I don't like the idea of ghosting here, coz it seems like you enlarged the scan and applied the ghost effect, which made the ghost-ed scan a bit grainy.

I like the colours btw, but the sparkles(filters) you put on Yuuko made people won't even put this wall as their desktops.

The background seems like unmodified stock (sorry if I wrong), the text didn't match the whole wall, the scan is a tad grainy, the wallpaper itself seems a low-effort one.

Suggestions :
1- remove the ghost effect
2- try different background and concept
3- limit the use of filters
4- try playing with brushes or textures for the background
