This image was captured on the plains of the Masai Mara in Kenya. We’ve all had a great situation ruined by a terrible background.  The sky in the zebra image was rendered as solid white and featureless. A cloudy sky with lots of detail was dropped in, adding lots of interest. The key is to use a more detailed/interesting sky, but one matching the overcast condition of the zebra image. A little layer masking, a blend mode on the sky layer, and the image is much better.
