Matt, I like them, they came out well! I like what you did with the tones, cooling it down but making the skin still feel pretty natural. The lighting is nice too, and I like the framing as well (might've left the hair in a little bit more on the left side of the last image and given a bit more room on the bottom on the first, but neither are opinions I feel terribly strongly about). For me, photos 3 and 4 work best; posing has the most to do with it. The way her head is tilted back in the first shot takes away the shadow under her chin and widens her neck which, to me, is unflattering for her. Her smile isn't really as genuine as the third shot (my favorite, for the lighting's shaping and her smile). The second image's head tilt feels a bit strong to me too, but it's a good image too. Nice work! I think the biggest things that got me were personal taste things and things you didn't really have control over, like her roots being a completely different color than her hair (which is the only nit for me in the third image), and me not being terribly into blondes
