I wish there are more career zoos

I'm not very good at building my own zoos in the Franchise mode. It turns out not very aesthetic. I have around 100 hours in the game but I still don't know how to build a decent look habitat. I just smack barriers and paths all over the place lol. I don't know how people manage to do such amazing zoos.

However I really enjoy the career mode. I've pretty much got 3 stars in each level. I like managing the zoos and not minding how to build so much, I hope there are more levels in the career mode that we can enjoy.
