To explain myself a littler better I mentioned free diving on reefs as opposed to the freediving on sleds in training and competitions. Those are diver oriented images as opposed to reef/fish/creature oriented. Many of the competitions are shot closer to the surface, getting on the bottom I think is a little more demanding regarding air consumption.
This is not the image improvement center but people still want feed back. I always mean to be helpful even if my honesty pisses people off. Frankly the pics above when I saw them looked very snap shottish noting as you stated you were getting used to the lens. The subjects were mostly centered, did not fill the frame, some cut off, a little blury etc. I left that stuff out. I thought simplfying a beginners setup would be more gratifiying and easier. I couldn't imagine myself taking pics even that good freediving in only 10 feet of water - This was where I was comming from.
Now after looking at your website it was like a different photographer Your not a beginner and the compositions on the site are far, far above these pics. The turtle compositions are really great. I completely agree with you on getting a better rig. You know what's going on.
This quote is intelligent and comes from someone who knows what they are doing and it applies to your website 100% but hope you agree not to the ones above. They are not awful pics by any means, but compared to your web site stuff you gotta cut me some slack on my asumptions. I will advise anyone else to check John's website out also.
