Hi, I particularly like the anemone, I think I agree aboout a tighter crop though.
I hope you will find like me, that there is lots of inspiration from other peoples work here.
I would love to have the courage and the money to take my DSLR underwater, fortunately the lack of the latter prevents me from worrying about plucking up enough of the former!! In the mean time I am still trying to get the best out of my little Canon A570. I have a long way to go...
Have fun and enjoy. Invariably I always see the perfect shot when I don't have my camera with me. I totally agree with you about wrecks, although I am trying to learn what all the different bits are!( It helps when you are trying to show other people around them!!
