Abhijat,
Maybe also try other levels of gradient so she does not appear to be popped into a vignetting cutout from a wedding photographer's album of 1930.
Also, does she need to be green? Not saying anything is wrong, because it's your vision that has to be met, not my opinions, LOL! Still it's appropriate to test how strongly these effects are needed as they strike us and give the picture, IMHO, a sense of artificiality. But maybe that's what you need to embed?
