Doug, how much post processing do you do? I think I detected it in the Cape Buffalo, the leopard in the tree, and some others.
Though they differ in quality (yours are much better than mine), it is amazing how we all seem to get some of the same shots! I had to reduce the size (hence poor res) of the photos below to post them here.
"Hey, nice wheels! What's under the hood?" A juvenile baboon sitting on the hood of one of the safari vehicles at Lake Manyara. Just before I took this photo he and his friend were licking the hood which evidently had been recently cleaned and waxed.

A Cape Buffalo in a small herd that was just below the rim of the Ngorongoro Crater:

A mated pair or two female(?) giraffe.

Maasai Warrior. Actually the village spokesman who is working on his degree at the mission school. He had an "Ironman" digital watch on his right arm and just peaking out below his traditional garb were a pair of Michael Jordans or khaki shorts! : )

A juvenile male, one of three lions trying to figure out how to cross a small stream occupied by (guarded by?) an ornery hippo. They wanted to join the rest of the pride so paced back and forth. His face was splattered with mud from an earlier, unsuccessful attempt. Though not graceful, they finally made it to the other side.

I use this photo as my laptop desktop. It reminds me of Marty the zebra voiced by comedian Chris Rock in the animated movie, "Madagascar":
