unfortunately for me trees and snakes do not respond to well to direction from a photographer
...
Here is the image she liked best, which I did PP in LR, the hair is messy, but that's where the snake wanted to be
I can see why. She looks -is- gorgeous. This is in my opinion the most successful shot so far. Her looks and expression, the curves on the snake, the closeness in crop that makes it possible to feel more "there" and appreciate the colors of the earrings and the top she is wearing matching with those of the snake.
The relationship looks better and more natural here.
I will suggest a little crop from the right side, just in line with the top, not showing the bare skin under to round up with a continuous eye path.
Trees tend not to respond to directions...
