Animal photography was one of the first thing I took an interest in, before I became a formal photographer. I looked at a lot of Andy Rouse photos and the likes, and then it faded. Of latest I've mostly only seen mediocre things around... that's why I want to comment on your stuff. I really like it. It's easy to ruin a good zoo image, but you managed to pull something really nice off here.
I like you framing, composition and tone. Pleasing to look at...
