That snow leopard's fur looks amazingly plush, I can almost feel how soft it must be and those spots are beautifully done. And the lazy, slouched pose of the black panther is perfect, you showed off the muscles very well. The more I look at it the more I notice those amazing little details like the reflection on the water, the subtle details on the coats of the two cats, the details on the rocks and plants, just all those seemingly unimportant things that really bring the entire image together and make it so much more magnificent. The way the trees fade out in the background is amazing as well! My only complaint is that the snow leopard's torso should be a little bit longer and the tail less foxish, but other than that it looks great all in all, beautiful piece.
