The jumping salmon is very crudely extracted, with very sharp edges and a noticeable outline from the original background.

The contest source cloning you did for the bear is likewise quite crude and repetitive in patterning for the chest and stomach. The direction of the "fur" looks sideways, rather than vertical, which makes the cloning job look even worse.

The "pendulous breast" highlights between the chest and belly are non-existent in real bears. They don't have two breasts that weight would emphasize like that.

This is a good concept, but you need to be better aware of what you are attempting to render. Perhaps looking at some grizzly bear images would help. You also need to put a bit more effort into "seamless" cloning that is not so obvious, as well as taking more time to extract images with a bit more care so they do not look so harshly "cut and paste."

You might also consider cropping at least 1/3 of the empty blue sky off the top. It adds nothing to you image except too much dead space which detracts from your focal point, the bear.
