Style: match the base exactly, with cartoon cel-shading, a dark-brown outline of the same weight, flat fills and soft shadows. Materials and colours come from the garments themselves (denim, flannel, cotton, corduroy, brass buckles), never the base's skin tone.
Character: a garden-gnome base, a stout bald man in THREE-QUARTER-LEFT view, cropped at belly height so the torso runs off the bottom edge. Draw every garment in this facing and perspective.
Fit: place each one exactly as the approved references jumper_11.png and jumper_12.png sit, at the same size, position and body fit, but make the designs new.
NECKLINE: the front of the collar crosses the neck at y=470 and meets the neck outlines at x=420 and x=645 with no skin gap. Nothing goes above y=470 in front of the neck. Draw only the front of the collar, and leave the neck opening transparent, with no back wall or lining.
Any V-neck is only a short notch.
BODY: the garment is fully opaque from y=470 to the bottom edge y=1024 and spans x=56..1016, covering both shoulders completely with no base showing at the sides. SLEEVES follow the base's actual arms down to the wrists. The VIEWER'S-LEFT arm runs from the shoulder at about (210,490) out to the elbow at about (110,740), then the forearm crosses IN FRONT of the chest to the wrist at about (330,700).
Draw that sleeve over the chest fabric. The VIEWER'S-RIGHT arm hangs from the shoulder at about (800,490) down the side to the wrist at about (860,900). Each sleeve is only the front half of a tube.
Leave the cuff opening transparent, and never draw the cuff's back wall or a band over the arm. Both hands stay fully transparent from the wrist: the left hand at about (410,670) and the right hand at about (890,960). Never paint a patch or box around a hand.
OVERALLS must include a complete shirt underneath (sleeves and shoulders covered), with the bibs and straps over it. Brass buttons and buckles are fine.
Range for the 12 designs: blue denim overalls over a red checker shirt, green bib overalls over a yellow gingham shirt, brown corduroy overalls over a cream henley, a red buffalo-check flannel, a blue-and-white checker shirt, a green tartan flannel, a classic chambray farmer shirt with chest pockets, a tan work shirt with a rolled-sleeve look (still covering to the wrist), patched denim overalls over an orange plaid shirt (rare), a striped railroad-denim overall (rare), a mustard checker shirt with a knit vest, and gold-stitched Sunday-best overalls (rarest).
No jewellery, chains or pendants on any garment. Hoods, if any, are down only. Nothing that sits behind the body.
