The one thing i noticed is the aardvark in the savannah habitat, which from a realism viewpoint you probably wouldnt see since you would need to dig proof the entire fence, a big expense for an animal you wouldnt even see most the time because its nocturnal.
So id suggest swapping it in for the nile monior (which isnt
really a arid species), idk maybe combine it together with the sandcat and fennec into a nocturnal house?
If you still want a monitor in the zoo id suggest to maybe include the asian water monitor in the indian reptile area

Probaly also wanna make the two gazelles switch places, makes more sense that way to me
Obviously you can do whatever you want, but you asked for thoughts and feedback so here they are
