Good photos, good model, good location.
My only advice would be to use slightly lower apertures. My experience has been that f/4 is usually around where I like to shoot to get the model looking nice and sharp but still with the background at a portraity level of out of focus and no missed focus. Especially when using something like a 5D2 where the autofocus system is kinda shitty.
I'll occasionally bokehwhore with an f/1.2, but f/4 is usually where I find I like the results best.
(Obviously this is subjective since you might just value shallow DoF over nailing focus and getting crisp shots more than I do, which is fine--like I said, I still really like the shots)
