Vision it sure is. Very good technically, in fact the detail in her dress and hair seems brilliant on my monitor.
Do you have other frames where her hair is framed a bit more with the darker tree background? I feel this may be a small thing, but somehow I think it might make an improvement.
This is a really great portrait. Very nice composition. I like the fact the camera wasn't level during the shot (atleast it appears that way! Sorry if I'm wrong). The light is fabulous. Well done!
