Shot in Kenya with film camera and telephoto from land rover. Scene only lasted a second or two and could not recompose.
The cubs were playing around the large male with one chasing the twitching tail. One became tired and rested his head on the Male's rump who objected with fang baring.
Given how fast y0u had to react you did well with the framing getting the important aspects in - the male's head and the little one whose it not clipped at all.
I would suggest a Shadow/Highlight correction to open up the shadows.
