Late night inspiration

This started off with the thought "I don't think mermaids would have human eyes." and I kinda played around with that. I'm not entirely sure if they would have hair, but I'm kinda doubting it since I don't currently know of an underwater creature with hair. I kinda played around with the idea of a half mermaid. The bottom one started out as another centaur, but then it kinda turned into this half bull thing. I like the half bull thing. The one I like the most though is the half mermaid.
