Lighthearted 2D cartoon illustration between children's picture book and webcomic styling. Crisp black ink lines of varying weight, soft sky gradients, and more painterly brush texture on the golden-brown dog versus flatter angel robes. Pale airy palette of sky blue, white, warm ochre, and bright yellow rings. A joyful dog runs left-to-right across a cloud layer while two small winged figures with closed-eye smiles stack on the right; floating rings and thin curved motion lines bridge the action. Bright even daylight with radiating sun rays and almost no heavy shadow. Rounded simplified characters, puffy wobbly cloud outlines, a speech bubble with a straight underline. Cheerful, innocent, playful heaven-and-pet energy with minimal environment detail.
