She doesn't need any tilt to add impact to the shot! A good sexy model shot, but I don't think the tilt really does anything either good or bad for this image.
Lovely colours and great focus. Lighting is great too. The tilted element is subtle.... perhaps too subtle for some and not really enhancing the subject
Couple of things, the one in the background is ditracting. Think it would be better without it. Also I think maybe a different color of dress. Like a comp color. Give it a bit more contrast this way. Think maybe even a black and white may have worked well here too. Other than that I like it.
