What do I think? I think you're a lucky man. The girl's got it goin' on! Her hair looks great,and she's all real. Your hair lighting looks pretty good, but I think the background lighting is a bit too bright. On the first shot, her tank top needs styling on her left side where there's a lengthy crease in the fabric. In the second photo, her leg position is not flattering.
Overall, the lighting is rather low-ratio, but yet yours light sources are not so huge that there's no definition; I can see that the edges of her arms and legs have some darkening, which adds shape,and you actually have her hair lighted quite well-ample light on the hair to see its cut and color, plus the nice accent light on the hair.
I think the area where the shots fall down is in the wardrobe selection; she's put together very well in key areas--face, hair, bust,nose, eyes,hair,waist,arms,legs,complexion,makeup---but the outfit she's wearing is not helping. With better wardrobe and slightly better posing, these would be really good. Your lighting, her makeup, all decent. But that high-waisted aqua skirt with the black belt is just not maximizing what's in front of the lens.
