One of my favorite dolls on Etsy is "Pamina" from Mozart's "The Magic Flute", made by AMCreatures shop. This artist captured the character beautifully, and his attention to detail is impeccable.
One of my favorite dolls of my own design is "The Summoning". She is my depiction of the Morrighan, a Celtic Goddess. She emerged very close to the image I was after. She is in my permanent collection.
