I think it's...decent? It's not amazing but not bad either, if not for the circles in the background I'd say it was just a scan with some text and colors on Lighten. Even now I think the BG could've used more light-colored (gray, green or blue) shapes here and there as it looks...empty to me.
I dig the whiteness - though to me it's too bright, so I'll have to tone it down a bit with some light gray. I for one can see the circles in the background (darker monitor settings help) though, again, they're too few. Not enough going on in the BG to balance out the scan and text, IMO.
As for the scan itself, the colors work. I can see some pixelation on her bangs (near the lily), this usually pops up when you use layers on Lighten over very dark colors. The girl is a bit grainy too, due to the scan's texture, so a light texture for the BG might've improved it even more.
