I'm intrigued as to how you managed to get this onto the system as it is 400kbs, double the normal limit. When I tried and upload a photo that much bigger, the system rejected it!
I think the pimped version of the pic is better as it decentralises the coral and gives the picture much more interest. I'm afraid though that the colours are good but that holds my interest for a very short time. After that there isn't much left to keep me interested. I think there might be some abstract mileage in the shot if you crop in very close, get rid of all the empty black spaces and use it as a contrast in the lines between the round pebbles and the straight lines of the coral itself.
Below is just an example but there weren't enough pixels to crop this much so the quality is poor. However, done from the original it would be possible to find a good crop. You could try a diagonal box crop (select and then rotate before cropping) to add more dynamic lines. Just a thought anyway.
Cheers,
