I really enjoy pointing my camera towards a light source so this works for me. Dare I say butterfly ears? I feel he is watching you take the picture. Perfect square composition!
I love this shot. It's heartbreakingly simple. The camouflaged rabbit, who you've caught out, is entirely winning and cunningly placed in the lower right corner. Here he or she anchors the subtle diagonal emanating from the brighter upper left. From your discovery you've beautifully pulled the rabbit out of the hat.
