After exploring the pack a bit more yesterday, I can give a bit more comprehensive overview (or close to it).
I've put down meerkats so far (fennec foxes are next), and they are absolutely adorable. Their animations are pretty awesome, especially the digging, obviously. I haven't played with other animals yet, but have seen them in videos.
I think the fact that everything is flexi-colour is just amazing. It does make sense that a lot of pieces can change colour, especially with this pack. Out of all the pieces, the first ones that caught my eye were the plaster arches and stairs, the wooden door, and the beautiful bronze-like fence. Oh, and of course, I cannot forget about the mesh fences - and the way they snap together without using the advanced tool.
I would have wanted to have more foliage, but it's not a big deal. My favorites so far are the new grass and the oil palm tree.
The features that we got in the update are such an improvement. The search bars are just...

Overall, I feel like I can't give an exact number rating, but I rate this pack highly. I think it's up there with the Aquatic & SEA pack. I feel like the more we progress, the packs are better because the updates are also better.
Anyway, here's a screenshot of a meerkat enclosure I did yesterday. I have seen some criticism over the big meerkat statue, so yesterday when I was building I really wanted to include it into the build just to see how it would fit (Frontier always makes beautiful scenery, but it's often very stylized, and I have a hard time putting into my zoos). I just sunk it halfway to the ground and hidden an animal talk point into the statue. I think it turned out great. (the picture was taken before I've put down the talk point so the statue is actually a little bit more raised, and I fixed some rocks behind it, but it pretty much looks like the picture)
