For me to keep them there needs to be a "WOW" factor, or they have to be a unique shot that I dont have in the every growing picture base. Otherwise they just are going to take up disk space. I agree with you Alicna I try to look at all of them and say "what should I have done differently?" Need to really work on lighting subjects, getting closer, less bulls-eye shots, ahhh everything. With bigger stuff, turtles, rays, etc... I need to get more in front of them so a little more emph is on the face.
Example: I like this shot but if I had been "more forward" and better lit, I think it would make it a much better shot.
