Beauty is a subjective thing, I know. In my scoring and comments I'm trying to score based on NOT whether or not I would think a particular subject beautiful, but on whether the photographer has succeeded in creating a beautiful photo. I look for the elements of color, lines, focus and dof interest, lighting, and a certain element of grace and lovlieness. I'm looking for a unique and creative appeal for the highest scorers. The description says to create a photo that makes the viewer think "that's beautiful", so it will undoubtedly be very subjective. (This is what I'm putting at the start of all of my comments, and I hope it is helpful.)
That being said, I think I might find this more appealing in person. The tones here seem really hot and arid. The large grouping of trees on the right rather dominate the photo and don't add a lot to the appeal. I would have liked something with more view of the water. For me, though, those orangish tones are the biggest drawback to thinking "beauty".
Overall the framing of this image with the palm trees is excellent. This image is begging to have something or someone in the foreground just left of the palm shadows as a main subject. Unfortunately, the post processing might have harmed the image more than making it more interesting. It also looks like the horizon is not quite level and high on the left side.
