Clean bold cartoon, thick black outlines, flat colours with one soft shadow tone, glossy highlights, warm playful palette. round sunglasses, aviators, nerd glasses, star-shaped shades, a monocle The base character's pose: facing straight at the viewer, both eyes level and looking at the viewer, head centred left to right; framed head and shoulders: the top of the head near y=210, the neck meeting the shoulders near y=740, both shoulders and the upper chest in the picture and running off the bottom edge; the arms are down and out of view, nothing in front of the chest; extra detail from the creator: looking straight at the viewer with a relaxed, confident expression; draw every item in that pose and perspective.

Anatomy of this character to respect: Cat ears stick up at the top corners of the head (around x 305-420 and 600-720, up to y≈245), so hats must sit between or over them. Wide fluffy white cheek ruff extends out to the sides of the head at eye-to-chin level; the neck is fairly narrow (x≈432-598) under a rounded chin.

Draw 16 glasses variants as separate 1024x1024 RGBA PNG layers for a generative PFP collection, matching the attached base character's rendering style, lighting and line weight exactly. Colours and materials come from the request and the item itself (felt, leather, brass, wool, glass, fabric), NOT from the base character's skin or bone: an item must never look made of the character's own surface.

Make the 16 variants clearly different from each other in shape, material and colour, covering the full range the request names.

Placement: WORN ON THE FACE: lens centres on the eyes at x=413 and x=598, y=468, each within 25px; bridge over the nose at x=512, total width 70% to 120% of the 440px head (a turned head foreshortens the pair); arms run from the outer edges of the frame to the sides of the head.

This layer is painted IN FRONT of the character, so never draw anything that should be behind it (the back of a hood, the back of a chain, the back of a hat brim behind the head): it would show in front. Only the glasses pixels; everything else fully transparent. Write artifacts/glasses_01.png .. glasses_16.png and artifacts/glasses.json: an array of {"file","name","weight"} with weights summing to 100, rarer lower.
