This is a great idea and a very good shot. But I feel that it could be improved – if only slightly – by changing the lighting. Try using bounced flash or reflectors to kill the dark shadows within the palm – your central subject. The composition is perhaps a little too central as well; try cropping the image to one side, this would – in my opinion - improve the balance of the of the very strong background over the central subject. Having said that, it's not a bad shot… (7)
Good composition, color, and focus. I think that the lighting is a bit uneven and thus the weakness of the image. Just a bit too hot on the right side, and too weak on the left. I think some fill light is needed for this type of shot.
