Style: storybook cel-shaded, bold dark-brown outlines matching the base line weight, glossy clay-like highlights, same lighting as the attached base.

Pose: three-quarter-right, head turned slightly back toward the viewer; draw every pair in that perspective. The near lens (viewer's left, x=475) is full size, and the far lens (viewer's right, x=590) is slightly foreshortened.

Placement: worn on the face with lens centres on the eyes at (475,240) and (590,240), ±25px. Reading glasses may sit up to 20px lower but still frame the eyes. The bridge sits at x=532, y~245, resting on top of the big bulbous nose (nose occupies x 505-600, y 250-320); never cover the nose.

Total width 108-324px (40%-120% of the 270px head). The near arm runs left to the ear at about x=385. The far arm is mostly hidden and may show a short stub toward x~625.

Goggles: draw only the front cups and the strap segments running to the sides of the head, ending at the ears. No strap behind the head, nothing on the forehead above y169, nothing below y311 except a tiny chain stub for reading glasses.

Content: 12 variants clearly different in shape, material and colour across the request, including: round wire spectacles (brass, copper, silver), round tortoiseshell spectacles, small half-moon reading glasses (gold wire, red frame), reading glasses with a beaded chain stub, and gardening goggles (green rubber with clear lenses, leather and brass aviator-style, scratched plastic, muddy goggles). Use item colours and materials, never the character's skin tone.

Lenses should be clear or lightly tinted with a highlight so the eyes stay readable.
