The serval is an excellent shot. Have you used USM in postprocess? I like the effect, but it might be a little 'crisp' for some.
The leopard's eyes need lightening and the nose isn't in apparent focus, which detracts from the shot - is the focus point is on the forehead so the available DoF has allowed the ears to be the sharpest point of the frame, or is it a blemish on the glass?
So, number 1 for me. Lovely shot.
