Thanks a lot! I just realized that the pictures in my first post are a bit small somehow, not sure how I can change this, I hope you can see more on the following pictures.
Here are some close-ups of the exhibits and so on:
That's the Giraffe exhibit, it was the first one I built. Initially it had a different shape but at some point I had the idea to build these elevated vantage points going into the exhibits so I built that and moved part of the exhibit (the big giraffe shelter fit there perfectly I thought) into the alcove at the top.
Behind the Giraffes I put Dromedary Camels and Gemsbocks, again with a vantage point that goes into the exhibit area while also separating them.
The Rhino and Elephant exhibits, here I had the idea to add some open space into the zoo, so I decided to built an elevated path around the exhibit and then create a small lake in the middle of the whole zoo area - which the guests could look at while walking around the exhibit.
Since I had a mod that adds bridges I wanted to incorporate it into my lake, it had the perfect size for it. Since a swimming shack would be a bit out of place in this zoo I remembered that there was a boat house, having guests ride around in swan boats on the lake was just perfect in my opinion. That's also when I decided to make the edges of the lake look a bit "untamed" and "overgrown", especailly in connection to the whole "theme" of the map being inside a city - bringing some nature into it.
Across the bridge there is a bit of a "visitor hub" with all kinds of stands, a map, benches and a restaurant (it's just crazy how much money these restaurants can make - both of them, one being near the camel exhibit, made around 150.000$ in profit already!). Since I was working with elevated paths so much already I tried to mix it up with a Penguin exhibit and add a water tank for them to swim in and then lowered the paths so guests could watch them underwater. I always love these views in real zoos where you can watch marine animals underwater like that. Right above the money counter is a little (modded) staff house with a car, I put it there because I didn't want to snake the path around even more (it was going in a straight line there which I liked).
Those two exhibits (the Saltwater Crocodiles and Anteaters to the lower left) were the last 2 I built since I had limited space. They are rather small and don't require that much space so I put these here.
Lastly, the (white) Tiger and (mexican) Wolf exhibits. The wolves were the 4th species I adopted and put right next to the entrance near the Giraffes. The Tigers I added because I just like Tigers and cats in general (and at that point I kinda needed the endangered species baby bonus lol). The bird house fit perfectly into an alcove again, added a little parking lot with a car there. In the right corner, not seen in this picture but the overview one, there is also a building (from a mod adding the developer items as purchasable buildings) with another parking lot that I added for somewhat of an administration building where the zoo staff is going for breaks, doing bureaucracy stuff and whatever else one needs to organize in a running zoo.
