There's a lot here to like but somehow all the fine ingredients don't quite reach Ella Fitzgerald's artistic heights (A very high level I admit).
I think it's to do with that fantastic sunset. If we see a wonderful sunset we are naturally moved by its splendour and seek to photograph it. This is a rare and beautiful sunset very well photographed but sunsets on their own rarely make a successful photograph. Is the subject the grass or the sunset?
I may be wrong but if we perceive something as 'beautiful' in the first place, a flower, a sunset K.Moss (?) etc then the bar is set high to begin with, ie our expectations are high and it takes a lot to impress us. For me some of the most successful landscape photography takes a mundane scene and makes it interesting partly because our expectation is low and seeing a different take looks interesting. If that makes sense.
