IMO this could have been better if you got a better exposure. There is a bit too much detail in the woman. Silouette effect is kind of lost. I would have also gone down lower to take the shot so the woman would be more part of the shot instead of a distraction.
Amazing landscape you have to play with there. The pose feels a bit forced though and I am not sure if I am digging the contrast of the shadowed figure to everything else. Nice image overall though.
