The only thing to be improved is the spacing on the ground. The two hind legs should touch the ground at always the same distance from the last leap, so the whole bear moves in small increments at the beginning and big increments at the end. You could construct some perspective grid on the ground, or use onion skin to place the bear correctly.
Wow! really good!.
Apart of the comments form slow, the keyframes are quite good! did you use any video footage as reference or is everything drawn from scratch?
