Cuphead game characters, retro. No cigars/cigarettes/vapes, I don't want to encourage smoking.

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; draw every item in that pose and perspective.

Anatomy of this character to respect: The head is an open-topped coffee mug with a flat rim at y≈272-310 and a handle sticking out on the viewer's right (x≈680-790, y≈340-590), so hats sit on the flat rim and glasses or side items must not cover the handle. Thin narrow neck (about 90px wide) joining a rounded, armless bell-shaped body.

Draw 16 mouth 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: on the face, centred at x=510, y=575 (the front of the mouth or muzzle as measured on this base: on a turned head or a snout this is NOT the head centre line), about 90px wide (the natural width of this face's mouth, measured: on a muzzle that is most of the muzzle front, never a small human mouth), within 399..621 by 532..652; large enough to cover the base's own teeth and lips, so none of them show around it.

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 mouth pixels; everything else fully transparent. Write artifacts/mouth_01.png .. mouth_16.png and artifacts/mouth.json: an array of {"file","name","weight"} with weights summing to 100, rarer lower.
