While on our big cat photo safari we had a lot of chances to get other animals up close too - the elephants are just so spectacular and so big and majestic - here are some shots from various regions in the area - enjoy
Elephants are such engaging animals. Yet it is hard to get great photos of them as eye contact is all but non existent...so getting shots like your second and last are the ones I love most.
IMHO I would crop a bit from the bottom of the second, putting the eles more toward the bottom of the image (I would do that for the third as well...closer to how you did it in the third shot)...
That is one intense rainbow...lucky you to have a great subject in front of it.

Eric - thanks for the comments _ I will try it and see how it looks - the first guy was almost in the truck that was close - I may try that as a square crop with just the eye area - I have another one like that too with a bunch of brown mud
