The somewhat desaturated look doesn't work for me here. It could work in full glorious color, or it could work in B&W or in almost-desaturated, but it doesn't work for me in this in-between state of saturation.
Another suggestion: I think the composition would be much stronger if you cloned out the palm trees peeking over the horizon, and just left the two kukui nut trees to focus on. The palm trees detract. Without them, and after changing the color one way or the other, I think I'd really, really like this one.
