This drawing’s always had a young girl-old woman effect on me. I see the creature as described, with its "tentacled, sphinctered mouth" facing forward (top left), but I also see it looking back over its shoulder, with a small, pursed mouth and a weird whiskered ear or Leia-esque side bun (top right). I can’t be the only one who sees that, I hope?

Holy shit! I never saw that before!
