Its like the theory of evolution....Fish>reptile>mammal...lol...I like the second one... I'd try to get some more light in his eyes so they pop though.
Thanks for the feedback guys! That is one of the reasons I decided to join here so that I may learn and hopefully grow in my new hobby/passion. The first shot was taken outside on a bright day. It is the right eye of my pet goose I posted a younger photo of her in my intro. The second shot was hard for me to get and it took several tries. I was at the Idaho aquarium inside and there a lot of actinic 03 (420nm) bulbs in there. It is also pretty dim inside there, they removed the iguana so that the kids could pet it. The last shot is a westslope cutthroat trout that I caught. The photo was taken on a bright day at around 6000 ft elevation.
