I'm really liking the Barracuda image and the stinger shot. Both are really nicely composed to my eye.
Like most of us, you might think about getting closer to your subjects on images like your moray and grouper.
Don't I know! Problem was, neither the moray nor the grouper had heard about "Get as close as you can. And then even closer", so they turned tail when I tried to get closer
Looks like you had a great time and did a great job for the first dives with the new rig. Congrats!
I sure had a great time, and thanks again
