Prompt
Create a whimsical watercolor illustration on a vertical 3:4 canvas with a deep navy night-sky background. Show a floating calico cat named {argument name="character name" default="Mitarashi"} curled diagonally in the upper left, large and gentle, with cream fur and soft mottled patches in {argument name="patch colors" default="golden caramel and muted sage green"}. The cat has pale green almond eyes, pink inner ears, delicate whiskers, and a calm affectionate expression as it looks down toward a tiny hamster. The cat’s tail transforms into a long, flowing stream of glossy mitarashi-dango-like golden syrup, curling in an elegant S-shape toward the lower right with rounded droplets and small floating blobs. To the right of the cat, include exactly one small cream hamster with rosy cheeks, closed smiling eyes, tiny paws and feet, holding and nibbling a skewer of exactly three round glossy dumplings colored amber-gold with one muted greenish dumpling at the bottom. Surround the pair with a magical star field: include exactly 9 larger four-point sparkle stars placed around them, plus many tiny gold dots like stardust. Use soft transparent watercolor washes, fine pencil-like outlines, warm highlights, gentle paper texture, dreamy storybook atmosphere, no text, no border, no watermark.
