A Shoreham big tide

I imagine there is a bit of HDR going on here? It may be a trick of the composition but the horizon looks ever so slghtly tilted CW. Also, although the position of the slab is perfect the marker pole is a little central for my tastes. I you can't open out any more (and you can't as you are at 24mm already) then moving back would have given you more sky (to drop the horizon below the midway point) and add a little more to the left to put the marker pole nearer a third, probably using a slightly more panoramic crop. It is a lovely photo though. Thanks, Rick

A really beautiful result, William!
