Chiaroscuro
Use strong, distinctly shaped areas of light and dark to model volume and establish visual emphasis.
Prompt
Use Chiaroscuro: a strong directional light from upper camera-left creates distinct connected shapes of light across the existing forehead, near cheek, hand, open notebook and coat, balanced against broad deep shadow masses on the opposite side. Make these shaped light and shadow regions describe the original anatomy and garment volume, with a few geometric light areas on the existing wall and ground. Avoid merely increasing global contrast; preserve illustration brushwork and all original geometry.

Effect comparison
In the baseline image, KaiMiren's clothing and the arcade occupy a fairly similar tonal range. Chiaroscuro creates broad illuminated areas on the face, hands, notebook, walls and floor, alongside continuous areas of deep shadow. These shaped tonal masses reveal the contours of both figure and space, and draw more attention to the action of the hands.
