I would prefer it to be less centered, do you have any more on RHS or you could add some canvas to RHS.
With regard to the bears eyes you could try lightening them a bit with a quick mask, I tried and it added a little sparkle.
I have done a quick image to show you my ideas, I hope you do not mind, the repost quality is not great and would be much better from the original RAW.
Lovely moment here Saurav! These Russian bears gave you some great shots. I agree with Ken's critique and suggestions...and think your repost is much better than your original post. I still think you can slice some space off the LHS to increase the dynamics of the placement of the bear. I always try to include more empty space in 'front' of an animal than 'behind' it
