Hi tanglewire~~
giving my 2 cents.
you said you were focused more on the environment. i don't really see the emphasis on it. i see more emphasis based on the "playfulness" of the model, there's also a weak emphasis that the model's the subject.
i suppose the only one that i would say is ok is #8, and #1. but #1 could be improved by getting more colors in (the colors are desaturated), placing her near the horizon and getting rid of the bush in front of her. because of the color, and what she wears, she blends in with the road and foliage.
and follow the rules of composition! rule of thirds, leading lines (#1 with improvements) etc.
