Paul, You got some great shots!
I love the lion "yawn"...at least I think it's a yawn?
Your comment about the bear's tongue is exactly what I was thinking.

I've seen bears on TV wildlife shows scarfing up ants out of rotting wood, but I never knew their tongues were that long.
I like the sharpness on the gator photo and the silky waterfall is very pretty.
My favorite shot is the white tiger except for that pesky group of distracting bright yellow leaves. If you're not too much of a purist, you might try cloning that out and you'll have a great shot IMO.
