This is a great shot. Would make a great stock shot. I would try taking this same shot with the yellow lines beginning in the lower right corner and placing the subject more on the upper rule of thirds area. This would show a bit more of the road ahead as well. It might be even stronger. Great the way it is though.
First off, always try to include some info about the shot in the Photographer's Comments section. It really helps out when we know what the photographer was thinking and what equipment/lighting/etc. were used, especially when you request a critique.
Camera Work/Technical: Wonderful depth of field, perfect WB and very crisp focus. I like your set-up and point of view for this shot, as well.
Lighting: Great exposure control for an obvious harsh light time of day.
Composition/Content: The best element in the photograph!! I like the sense of anticipation that this one gives me as a viewer. I just think, "man she's got a long way to go," and anticipate seeing her next step. The centered composition works very well, but I would like to see her head a little bit further down from the top of the frame. Not much, but she seems just a little cramped.
My Opinion: I really like this image. I mean really, really, really like it. I scored it a 5 because I don't see it as an environmental portrait. It is a GREAT capture, but an environmental portrait needs a face and an expression. In a different challenge, this is an easy top 10 or 20. That's my opinion. I hope it helps out a bit.
Nice shot...I like the hands in the back pockets. I think I'd like to see this shot on a curved road or maybe just from the left a little more so that you can see way down the road.
I like the picture - composition, brilliant colors, nice scenic. It strikes me more as a scenic with the girl as a prop rather than a portrait of the girl with the scenery as background.
