This has the potential to be a top 10 image but I think it's composition has let it down. You've retained the shadows at the bottom of the frame as an interest point but I suspect they are competing for attention with the awesome top-right part of the image. I would be interested to see the result of a crop that just cuts off at the shadow's tip. That would leave the red flower on a thirds intersection in a landscape format and it would share with us the outstanding textures and colours below the surface.
i would have liked to see this image with the reflections at the bottom cropped out...to really direct one's eye to the still water surface and leaves.
More fall under water... its really here isnt it? For me and in my opinion only.. I think i would have cropped the bottom of the picture more.. to put more focus on the bright red leaf and the ones under it...
