I don't remember whether I was a fan of Peter Rabbit growing up. However, in my early teens my family adopted some rabbits and I spent many, many hours just observing them. Ugly, cartoony, anthropomorphic rabbit drawings became my pet peeve. Some time later, I noticed some illustrations by Beatrix Potter and thought to myself, "she really understands rabbits." A kindred spirit.
Beatrix Potter's animal characters are extremely realistic, but still cute and expressive. I respect her work a lot.
