Looks like the ears are just tilted back at bit / posed differently in the initial one to me?
And omg, I am loving this update and DLC! It's such a small thing, but being able to remove the entrance and put it someplace else is a game-changer for me (I only play in franchise mode). I love having it just in the middle of the map instead of at the edge of it, and being able to build around it and theme it to fit my zoos.
I haven't had the time to use all the new animals yet myself, but what I have seen looks great!
New morphs are also a great addition, especially the king cheetah. Best cheetah.
