Retro UPA Cartoon Style

Transform this image into a cartoon-style modern illustration inspired by classic UPA animations like Mr. Morgan and Space Family.
Redesign characters with flat geometric shapes: ovals, rectangles, simple curves, and angles. Avoid realistic scales—the design should be stylized and abstract.
Use a limited palette, preferably soft pastels or striking contrasting colors (such as mint green, salmon green, sky blue, mustard yellow), and use flat tones without gradients.
Simplifying facial features and body structure to make them iconic and minimalist—big head, small limbs, expressive poses, but with very few details.
Backgrounds should be minimalist or symbolic, using basic shapes or abstract scenes (floating stairs, block furniture, stylized trees, or stars).
The final image should look like a frame from a 1950s or 1960s modernist cartoon—lively, graphic, and highly stylized.
