I am very sorry to say, but probably this is not going to improve much...
- Really nice!!!
The tilt / OoF background gives me a hint of outside in be back / front yard and doesn't distract too much at all, IMHO a good balance.
Your daugher is beautiful (of course) and a decent smile (could maybe be slightly less tense), but the twinkel (light reflection) in her eyes is simply great.
- Composition wise I would consider to crop a little from the bottom and after looking at it a little longer a little space on each side of her shoulder would also be worth considering, but don't know how it would work with the nice tilt.
Either way: great portrait!!!
- Thanks for sharing
PS: Did you do this tilt on purpose? Really nice aspect!
