Hand Drawn AnimaIs

It's a collection of 5000 hand-drawn animals on the Ethereum blockchain. There are 4 different types: 1250 cats, 1250 lizards, 1250 raccoons, and 1250 dinos. Why did I as an artist pick these types of animals? Cats represent domestic animals, lizards represent cold-blooded animals, dinos represent extinct animals and raccoons represent mammals.
