First underwater pics - cold green water

Hey all, I just got back from a short trip last week up to British Columbia. This was my first time back in the water in 8 months as well as my first ever with my camera gear. The first 2 dives went ok, but were mostly just getting comfortable with it...and after that I felt at one with the camera. My shots were taken with 20D either in Tv or Manual mode using the Ikelite TTL. I was using a Canon 10-22mm set ~20mm and a 60mm macro.

Any pointers are appreciated. All images were simply ran through Aperture for levels and exposure adjustments, shot in RAW.

I can't decide which I enjoyed more, macro definitely slows you down and makes you more observant. I took a total of ~700 images on my 8 dives. I don't recall the water temps, but it was cool...but even on my last dive with well over an hour in the water and 45+ minutes submerged I didn't notice in my warm and *dry* suit

I definitely have plenty of shots that aren't worth sharing. Back scatter, exposure, light fall, and other problems I had expected. I was please with the number of "good" images I came up with. I need to clean some more up (back scatter around jellies, etc) and add them online. My entire gallery is here: http://rec.smugmug.com/gallery/3851387/3/222885459

Thanks for looking, and thanks in advance for any input.

Images 6,7 and 9 are my favorites. No backscatter at all with the jellies and a nice "climbing" nudie. I think the anemone and sea star pics need a more exciting composition, and maybe a little more close.

I think you could do with a slightly less intrusive copyright sign tough.
