Chunky pixel art on a 32x32 grid scaled up, every pixel a hard square block, no anti-aliasing, no gradients on the character, 1-pixel black outlines, limited retro 16-colour palette. hoodies with the hood down, plain t-shirts, a puffer jacket, a tracksuit top, a denim jacket, in bright retro colours 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, relaxed confident expression; draw every item in that pose and perspective.
Anatomy of this character to respect: Messy brown hair rises to about y=192 with stray tufts, and brown sideburns sit at the head edges by the eyes. The neck is long and narrow (about 448-576 at its base), so collars and chains sit low, near y=720-740. Draw 16 jumper 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: A COMPLETE GARMENT WORN ON THE ATTACHED BASE, at eye level in the base's own facing and perspective: the base's neck passes DOWN INTO the garment's neck opening and the collar wraps AROUND the neck. Leave the neck opening transparent where the base's neck is (around x=512, from the jaw down to the front edge of the collar), so the real neck shows going into the garment.
NEVER draw the inside, back wall or lining of the collar or neck hole, and never fill the neck hole with fabric: that makes an empty garment sitting in front of the body. The front of the collar may overlap the lower neck.
Neckline (where the collar crosses the neck) at about y=730 (the base's neck line is at y=672); the garment runs to the bottom edge y=1024 and spans x=0..1024 (40px wider than the shoulders each side); COLLAR FIT: the neck opening is exactly as wide as the neck itself, from x=448 to x=576, hugging it with no gap of skin between collar and neck and no fabric over the throat.
COLLAR HEIGHT: the collar ring wraps the BASE OF THE NECK, where the neck meets the shoulders (around y=730); a crew neck or hoodie collar crosses the neck just there, never down at the collarbone with a long stretch of bare neck or chest above it (a V-neck may dip at the front, but its collar still wraps the neck base at the sides and back). NO jewellery, chains, necklaces, pendants or chain prints on any garment: those are a separate layer.
HOODS are only ever DOWN, drawn as a soft rolled collar lying on the shoulders around the neck; nothing of a hood rises above the neck base behind the neck, and never a hood up. Opaque everywhere on the torso and shoulders so the base body never shows there. Collars, lapels, scarves and necklines belong to this layer.
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 jumper pixels; everything else fully transparent. Write artifacts/jumper_01.png .. jumper_16.png and artifacts/jumper.json: an array of {"file","name","weight"} with weights summing to 100, rarer lower.
