My overall impression of this shot is of an opportunity lost. It doesn't help that the man is in the shade but I feel something much more darking could have been done with the composition - the scenery alone doesn't add to the mood you've so nearly created. If we could see more of the man I feel it would help.
The guy is just too much in the shadows, it actually took me a little while to even notice that he was there. I like the subject though, this is a great point of view.
