I am going to assume you aren't requesting photoshopping ideas, but rather if we think the shot itself is worth spending time editing.
I like it, I see a lot of people shooting high key stuff and blowing out the sky lately. The composition itself is nice, I like that the flowers in the foreground keep her dark shirt from melting into the background. I'd probably blow out the sky completely, rather than leaving that one cloud there which draws attention to it. Oops, now I'm giving PS ideas.
