Great animals!
I tried both your dilophosaurus and brachiosaurus and Borsato´s versions, and I think it´s quite hard to choose which one to use.
I was just thinking, maybe you can rename your dilophosaurus to sinosaurus or dracovenator, and/or brachiosaurus to some different brachiosaurid, so it wouldn´t look weird when having them all in the same zoo?
PS: that´s just a suggestion, there´s nothing wrong with having more versions of one animal. I also made my own versions of crowned cranes when I wanted different compatibility for them.
