Beautiful artwork! This is an instant !

I love the textures. The trees all look amazing, and I love how the coloration gets darker and more blue with distance. It gives this a ton of depth and really sets the mood. It also makes the character really stick out from the piece. You've drawn the tree bark amazingly well, much better than I've ever been able to.

The coloration and anatomy of the character is awesome as well. I love how you've indicated the musculature of the shoulder and side with the shading. The character seems truly alive! And a bit frightful with that scary spear.

Awesome job, through and through. The only suggestion I would have to make this better would have been to add some sort of bank to the stream. It seems unnaturally abrupt how the water magically ends and grass begins, almost like the strip of water is a solid thing, frozen there. The water itself is very well drawn, it just doesn't connect very naturally to the rest of the scene.

Wow, this looks really nice.
Quite detailed, and your way of doing trees is really good.
The cougars anatomy is quite good as well.
