Thank you for your comments, I appreciate them! I don't know about the sharpness, maybe it's the smaller version that I uploaded here that is not sharp enough on screen? When looking at 100 % on the full size image it's really really sharp, even in the corners. Some parts of the image is not as sharp obviously because of the water. The seaweed in the center of the image is not as sharp because of a wave crashing over during the exposure. With that part sharp aswell it would've been an even better image I belive.
