Draw 12 steampunk baggy upper-body garment variants as separate 1024x1024 RGBA PNG layers for a generative PFP collection, exactly matching the base character's painterly style, ink line weight and palette (dark leather, teal cloth, aged brass, bone). Character is FRONT-FACING (eyes glance to viewer's right; body is square to camera).

Skull: top y=432, widest x=290..735 at cheekbones, jaw bottom y=845 spanning x=360..660; eyes at y=632 (x=425 and x=610).

Placement: garment covers shoulders and chest across x=0..1024 from the shoulder line (y=890 at x=0 and x=1024, rising to y=760 at x=215 and x=805) down to the bottom edge y=1024. Neckline sits under the jaw: neck opening x=370..655, top edge y=790..830, so the jaw (y<=845, x=360..660) stays fully visible and is never painted over. The garment must be opaque and fully cover the base's existing leather coat, lapels and brass collar in x=0..1024, y=760..1024 outside the jaw area.

Variants: baggy cable-knit jumpers with brass buttons/patches, chunky roll-neck jumpers, oversized knit with gear embroidery, hoodies shown with hood DOWN and bunched behind the neck/shoulders (hood fabric only below y=800 and outside x=360..660 above y=845), and baggy open-collar shirts worn over a jumper or vest (no exposed ribcage gaps). Add brass gears, rivets, teal gems, leather straps, pipe trims as flavour. Only garment pixels; everything else fully transparent.
