Ha ha. First I thought its a dog and somehow managed to climb up. :D I love its ears. I am tempted to crop from the left till the tree trunk. Overall, I like this one.
The pose makes this image in my opinion. I am not sure I have seen a picture of a bear cub sitting like this. This cub certainly project character. I think you handle the light well with only the shadow on the cubs neck showing some blocked pixels however, I personally do not mind much as the rest of the image more than makes up for it in my opinion.
