It's a bright and happy image, with nice subjects (the two "\\" trees) and full of green tones, I think it lacks a spot of different colors in the little tree or on the grass (some bananas, a flower or a simple colored object). Bye Max
I think what went wrong is that there is too little banana plant in the image. It is dominated by two dramatic coconut palms. Try a different viewpoint shooting through the coconut palms and moving or zooming in so that most of the frame is filled with the banana plants. Also, may be rotate the camera quarter turn for a vertical or portrait-mode composition.
