I have a visiting black cat quite often, probably younger than Moriarty, a tuxedo one, immensely playful and powerful. I find myself in an impossible position to photograph her like you.
Here the composition is masterly but I've no idea what gear you used, what light, what ISO. Granted, I am very lazy when it comes to use any type of lights and have almost none. But I am a poor photographer, at least form the technical point of view.
I marked this with 8 for now although it is best in the show on a par with another one. Perhaps I'd like to see more of his left ear, or his sly look ...but kudos for the composition and its implication
