I'd rather comment on one or just a few images then an entire trip worth of shots....(even though cut down to 70) . That i make comments doenst mean I can do it better, just some thoughts...
General:
* is it the onboard strobe that leaves the top half of the image a bit lighter then the bottom half?
* There are a few images when a little post-WB might be able to get rid of the blue cast.
* composition sometimes too center -oriented (subject in the middle), but other times very nice
* sometimes the fish are swimming away, its nicer if they swim towards you (might be the shutter delay)
I really like the anemone fish with the diver, although you might want to consider a more attractive diver
I also like the close up of the clamps mantle, and the second last sunbeam shot. I feel you could have tried some more variations there to come up with a more diagonal composition.
