I live in Western Canada where mountain lions/cougars (sometimes called pumas) are a part of the environment. They are a hazard and there is a saying here when you go hiking "You see a cougar once - you're lucky; you see it twice - you've got problems as it's hunting you." Because the animal is cautious and careful most pictures of cougars tend to be pretty static with it just wandering along a trail or snarling from a tree.
Your picture pays homage to its true nature. Technically I see no flaw. The cat is in strong dynamic motion yet the focus is razor sharp with no hint of blurring. The colouring is natural and when combined with the blurred, subdued background allows you to study the animal in detail. How could you not admire the intense gaze in its eyes, how it powers off its back legs and the extension of its club-like tail for balance. Wonderful picture that will become one of my favourites.
It is a good picture of the cougar but the placement of the animal is a bit bothering me, being in the middle and the head facing the end where the action is going to take place, makes me feel like I am out of space, you should have cut it so it would have had more space for the cougar to make the leap towards to, what I'm saying is that my problem is with the composition, you could look up a few basic composition tips when making a photograph, I hope it's a constructive criticism...sometimes it's okay to break the rules, but this picture could have had more space overall I like the colors and the sharpness and the cougar has a nice expression and pose too, like it's leaping towards me keep up the good work! wildlife photography is hard!
