They are nicely positioned in the first two. Do they like to pose like that?
Would they do it again for a re-shoot? So you could try to get both faces into the frame like in 2, but with the top cat having his ears and the one below having his chin?
Nice close-up of the paws, maybe their fronts should have been in focus instead of the legs in the background?
I have often tried to get such close-up shots of my cat, too, it is great fun, isn't it?
