#3 is nice although the colors are a bit saturated for my tastes. The crop on #1 leaves a lot of "emptyness" on the left side. Maybe a different crop? #2 would have been a GREAT photo but it appears the shutter speed was not fast enough to get a sharp image. I don't mind the fish being a bit OOF, but the heron's eye is not sharp. Unfortunately the OOF vegetation in #4 spoils it for me. In #5 the bird is looking away from the viewer.
