Although this image might be a bit much for some I think it does tell a story of day to day life in the African bush. 40D, 100-400, ISO 400, f4.5, 1/320, fl 115mm, 95% full frame.
That's pretty raw Stephen. I would suggest cropping the top down to the grass. I know that makes the image square but the tree stump and tree line is distracting. Cropping will focus attention on the lion and kill.
