Im no where near a professional or a really good artist but I do have a good eye for Perspective;
The is so beautiful, its one of the best I've ever seen, but I did see one thing right away, the water/pool, immediately below the lady slopes down to fast.
imo, not too hard to fix the easy way; In PS I would 'feather-select', horizontally at the top water line and under the ladies out cropping. Then I would 'transform' vertically from the bottom, up about a 1/2 inch or so. Then 'resize canvas', do a little touch up.. Done!
Like I first said, its Awesome Beautiful!!! So, no big, just leave it!
