As for pose, she was leaning with her elbows on a deck railing, looking down at the river below, which at the time appeared as a perfectly natural pose.
The color of her eyes is natural. I am attaching a crop with before (out-of-camera raw) and after post-processing.
I actually turned the magenta saturation down in post-processing, as well as made it darker, but I thought that the hoodie and its color in general balances well with the whole.
