The comments about eyes and ears from Art and others sent me back to my archives here is one from the next frame. It also led me to find out I was crediting the wrong reserve it was taken in Lebala, Kwando Reserve.
Also it was EOS 1D MkII not 10d.
100-400 at 400
F11, 1/200, ISO 200
Thanks to all I have discovered a slightly better image (I hope)
Thanks for the comments, these photos are mainly down to the totally accomodating nature of the three brothers plus a wonderful guide Steve K, and of course a little luck.
Stare and uniform colors are unusual but make a very good presentation. The ears back look like he/she is not very happy. Perhaps a little sharper would be nice?
Thanks to everyone for their kind comments, I love this picture nearly as much as I did the Cheetah in it, sadly he is now dead, but I will always have the memories.
