Still have to get use to seeing the high ISO UW f 11 at 1/60 was more the norm :) btw since you have the ability try stopping down to f 22 for the sunburst effect, works great UW.
Classic close up wide angle image and sure got some even light on the sea fan !!! Big Congrats !!!
Classic sea fan shot. I love the subtlety of the sun burst. As Alfred says, very impressively even lighting on the fan especially with a single strobe. Nice one.
Cheers.

EDIT: I might try and do something about cloning out the bubbles.
