I also like #4. You are showing us a pair of animals completely at ease with each other. It's an unusual pose and beautifully processed. Good luck with the contest.
Number 1 for me. Help me out. It seems as though a lot of people like 4 best. What am I missing? What makes 4 better than 1? Is it just a personal thing or is there something specific that I don't see which makes 4 better?
