I love shooting outdoors and with ambient light. One of the challenges of doing so is there is less control than in a studio (or even an indoor setting)....planes flying in the air, telephone lines, garbage on the ground or mottled light on the models (so they look blotchy and uneven). You've done a very good job here for an outdoor shoot.
I like both poses. First shot, her jawline disappears--it would be stronger (and a better shot) if her chin was turned another 3 inches to her left (your right).. Second shot, I'm not wild about her expression. But otherwise, both are lovely pictures.
