Gekritzelte handschriftliche Porträt-Illustration

An analog paper-and-ink illustration on a [white paper background] covered entirely in dense, frantic black ink scribbles, chaotic handwritten notes, loose formulas, mathematical symbols, arrows, slashes, and ink splatters. The subtle silhouette, eyes, and facial expression of [character's face] emerge organically from the varying density, clustering, tonal contrast, and negative space of the chaotic marks, without any distinct outline or direct realistic portraiture. The face feels assembled purely from fragments of the surrounding textual chaos. Text fragments include semi-legible Japanese characters, Latin letters, and numbers. Splashes and marker blocks in [red-ink] provide occasional accent emphasis, underlines, and highlighted patches. Tactile handmade notebook page texture, restrained monochrome black and white palette with sparse red highlights.
