Dark fantasy illustration, heavy black ink outlines, dramatic rim lighting with glowing highlights, flat cel shading with gritty texture, a palette of void black, bone white, ember orange and ghostly teal. a wide skeletal grin with every tooth, a jaw hanging open in a silent scream, teeth clenched around a candle, a jaw stitched shut with black thread, a grin with a glowing green tongue, a single gold tooth in a sneer The base character's pose: head and body turned about 40 degrees so the face points to the viewer's right: the far eye partly hidden behind the nose, the far cheek narrower, one ear visible; framed from the crown (near y=110) to about belly-button height with the arms in frame; the body continues PAST THE BOTTOM EDGE of the canvas: the frame crops it at about belly-button height, so the torso runs straight off the bottom with no visible end, outline, rounded bottom or empty space below it (never a floating bust); arms relaxed at the sides, nothing in front of the chest; extra detail from the creator: head tilted slightly down, looking up from under the brow, a slow menacing stance.
FOR THE BASE ONLY: the hand that will hold the item is raised OUT TO THE SIDE of the body at about shoulder height, the upper arm angled away from the torso and the forearm upright, so the hand and forearm are entirely clear of the chest and belly and never cross in front of the body; the hand is in a loose EMPTY grip, fingers curled around nothing; the other arm hangs relaxed at the side, and the item itself is NOT drawn on the base: it is a separate In hand layer added later; draw every item in that pose and perspective.
Anatomy of this character to respect: Bare skull with no ears or hair, tilted down and turned to the viewer's right with a long tapering jaw ending in a point near y=560; the neck is a thin exposed spine set behind and left of the skull, so collars and chains wrap the vertebrae and rest on the collarbones around y=640. The torso is an open ribcage with no flesh, so clothing must drape over bare ribs.
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=545, y=515 (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 50px 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 458..632 by 489..561; 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.
