Masaii Mara National Preserve

I want to know what I can do to improve. I realize I should have

used a ND Graduated filter, but the shy was pure blue. I am unsure

it would have had an effect.

Excellent photo.... maybe try to crop out a little of the sky. now your eye tends to stall right above the hill. try to make the lion the focal point (just my humble opinion

you could definitely crop a large amount of that sky and make this a horizontal shot.
