Javier, I'd be proud to have these in my portfolio. She's a beauty now, can't wait to see your wedding photos of her.
Graffiti: I go back and forth on removal. It *was* there at the shoot. My personal tastes dictate leaving more "artful" graffiti. This graffiti looks like a child's.
The missing balusters: you might be able to select the left baluster, copy onto two new layers, then reposition.
To further nit-pick, the left column behind her leans to the left. Photoshop's lens correction or actual, selective distortion may tame that.
I agree about boosting colors in her gown, an/or adding contrast.
