"Make me a high-quality 3D render of a [INSERT ANIMAL HERE]. I want it to have a Japanese kawaii art style. I want it to have nice, big, expressive eyes, a nice smile. I want this to have a strict left-side orthographic view. I want the animal to be resting on its belly. I want the nose to the tip of the tail to make one straight line. I want this to be ready for STLBuddy."
