Bill,
Comparing these to other images on your site, these two aren't of the same caliber, for example the shot of the eagle rays. One question you might ask yourself is why do you like them? I have a couple of similar shots of spotted eagle rays that I'm on the fence about as well, and while they aren't technically "good" shots, I find myself keeping them around. I think in my case, it's because they remind me of a very good dive, and have some personal significance because the encouter with the eagle ray was awesome. Other people looking at them don't always feel the same way, especially non-divers, because they weren't there, so there's no attachment to the moment. I sort of get the same feeling from these two, that they are keepers to you for personal reasons that I as the viewer don't see.
Does that make sense, or am I just in dire need of some coffee this afternoon?
Tom
