The picture are kinda small so hard to see. It looks like you've blurred her face a bit too much.
I would add a shadow under her feet - I know there isnt one to begin with but you cant see the heel of her shoe either so she looks like she's kinda floating and when you're altering a photo you have to pay close attention to things that have occured in the real photo that already make it look manipulated.
Really you need to post bigger pictures so we can see the detail
