I also really like the angles you've captured. Also of interest (at least to me) is the pattern that the poles make in the water as well as the general monochromatic boat covers (with just a few white ones to make it standout). Composition is great too! The only thing I could suggest for improvement is perhaps a polarizing filter to get some detail out of the sky.

Nice shot. I like the angle and perspective. I'm going to be going there in a couple of weeks! I hope I can get some good photos like this while I'm there.
