Prompt: A black-and-white minimalist hand-drawn grid of character avatars, strictly divided into 6 rows and 4 columns, totaling 24 portraits, evenly arranged on a white background. Key structure: Each avatar is framed by a square grid, with the four edges of each square forming the contour boundaries of the person's face. The face fits closely against the four edges of the grid, with no extra margins. Style features: Pure black-and-white line illustration, no fill color blocks, no shadows, no gradients
Hand-drawn texture, slightly irregular lines, and a quirky and innocent editorial illustration style
Minimalist features: polka dot eyes, small circle eyes, short eyebrows, small dotted nose, straight mouth, small smile, slightly sad mouth, sleepy eyes, surprised O-shaped mouth, expressionless face
Hairstyles are outlined by lines: wavy bangs, curly cuts, center-parted curtain hair, crew cuts, sided bangs, swirl curls, striped hair, and scallop-shaped bangs
Some characters have round glasses, square glasses, beards, freckles, closed eyes, and X-shaped eyes
The characters' expressions vary: happy, sad, confused, sleepy, surprised, expressionless
The overall style is close to a hand-drawn character guide: geometric, restrained, innocent but not loose, flat, high contrast, colorless, no background decorations, no realistic details.
