Some people might be a little confused about what characters of mine fit in each category. It's pretty simple right now. But, I might change some things around the more I draw my characters.
Characters that are in the bird family.
Characters that are in the dog family.
Characters that are Hybrids or that don't fit into any of the other categories.
Characters in the cat family.
Characters that are based off of different Pokemon species.
Characters that are Reptiles, Dragons, or similar. They don't necessarily need to have scales.
Characters with hooves.
