Riaan,
Good for the soul and soles. These places are the life pleasures. I see what Walter is saying. The longer I looked the more I questioned why it was so alive, but held back... Finally, covering the severe limb squarely into the upper left was the culprit. It just grabs on to the dynamic flow and locks it there in that corner leaving the subtleties of the rest of the frame unable to stand their ground.
Can appreciate with the sun (earth) changing the opportunity for the shot not a lot of chance to work around it, but a careful look at the edges of the frame in the viewfinder or on screen might have freed the dynamic. Just block out that left corner limb and see what you think. Thats the hitch of the image for me...(and wish my legs were in that sea, thank you)
