I stumbled across this fantastic Tumblr full of traditional hand-drawn animation, and I can't get enough of it. Artist Willow S. Linda reinterprets live action and cartoon characters in her own style, like these Star Wars portraits or this Beauty and the Beast design. But she also creates her own characters too. The first one that caught my eye was this delightful little story of a mermaid and a centaur.
There's just so much whimsy and joy to Linda's art, I could look through it all day.
You can find all of Linda's work on her Tumblr.
