Good good, good luck with that. Maybe really try something like encircling an area in your zoo and then plan how you will split it up into multiple habitats and how you will deal with both shelter and staff entry. For example from the zoo that im building right now, i have one big not so empty anymore spot in the middle that the mainpathway circles around, that also gets cut in by a guest and a staff path. Right now it is filled by penguins, babirusa, kangaroos, giant anteaters, pangolins, nyalas and dallsheep, with me planning two habitats, one for meerkats and one for banded mongooses as well.
If you look into the thread of my zoo, i allways incorporate a shot from above,where you can see how the middle is slowly filling up, while the edges are pretty much unfinished, something that will propaply stay that way till i have completly planned out the zoo, which is also why the giraffes are unfinished, as i dont know if there will be something next to them on the hill.
Another thing thats added this way is a natural panorama, that just fills out the more you build. If everything is somewhat connected, you can have extremly unexpected views, that are totally stunning. For example i noticed that the view from the staff path above the kangaroos down the hill over the kangaroos, penguins and into the giraffes is beautiful, making me consider to make atleast a bit of it accessable to guests.
You will quickly find out how much more gorgeous it will be, when the stuff you build does not only look good on its own, but also is surrounded by beautiful stuff you also build.
So yeah good luck, cant wait to see what you will do ^^
