Great composition and from an ideal vantage point. Just one niggly - this being sunset and all - the foreground seems to bright and lacking in contrast. In particular the grain/bark of the foreground tree looks washed out. While I realize you might very well be working towards a certain effect, it appears (to me anyway) to be not quite "real" in an image where it appears you are working towards realism. However, at the same time, I appear to be in the minority (or are we, as a forum, shying away from constructive criticism?)
