Style: storybook garden-gnome cel shading, shiny clay look, bold dark-brown outlines, flat fills with one shadow tone and glossy white highlights, same line weight as the base. Character faces slight-right (head turned a little to the viewer's right): the viewer-left lens is slightly larger/nearer, the viewer-right lens slightly foreshortened.

Placement (match the approved glasses_06/07/08 exactly in size and position): lens centres on the eyes at x=475 and x=590, y=240, each within 25px; bridge at about x=522-533, y=245, resting above the big round nose (x 550, y 285) without covering it; total frame width 120-360px (40-120% of the 300px head); left arm runs from the outer frame edge to the left ear at about x=385, right arm short, to about x=625.

All pixels stay within x 342-702, y 169-311; nothing on cheeks, nose or skull outside the frame. Both eyes covered by lenses, centred on the face, never low-set.

Variety: 12 clearly different designs across the request: round spectacles (e.g. thick tortoiseshell, chunky enamel red, twig-wood rims, brass rivet frames), little reading glasses (half-moon, small oval pince-nez style, tinted green), gardening goggles (leather-rimmed with brass, rubber dome goggles, mushroom-cap tinted). Do not repeat the same shape in a different colour.

Goggle straps: show only the short strap ends running from the frame to the sides of the head at the ears; never draw the strap behind the head.

Lenses: glossy semi-transparent glass with a highlight, eyes visible through clear lenses; tinted lenses stay readable. Colours from the item materials (brass, leather, wood, enamel, glass), never the skin tone.
