[Marc, first of all you don't have to buy my time! I'd love to help you get more enjoyment from something you obviously have a passion for. Perhaps when Gary is ready for his portrait you can swing by and I'll put on a little workshop for you.
Second, don't be so tough on yourself, your shots are looking great and getting better and better!
Third, I think the aperture priority mode suits you well. I really saw big improvements in your depth-of-field and overall focus of those pics you just posted on your site. Getting that clam in focus at that angle was no easy task and I can tell you're starting to get a feel of what you need to do.
Finally, on the full tank shots, a piece of friendly advice. That first one you posted was very nice, better than you give yourself credit for. If you want to improve that shot, think about perspective. There was an obvious downward angle versus looking at the tank dead-on. Being a 28-year old with a back worse than most 50-year olds, I undersatand your reasoning.
But drop the $40 on a tripod and that problem, as well as the hand-holding thing, will be solved. Trust me on this one, it will be a very worthy investment. As you explore aperture priority it will become more and more obvious that you need a tripod.
Finally finally
: Looking great Marc! Keep shooting, you're really getting there. Keep in mind your camera is digital, each photo costs you nothing, so don't be so critical of yourself and remember to PLAY!
