Portrait in Coffee

{
  "prompt": "Transform the portrait into a hand-drawn illustration made with coffee on textured paper. Use natural brown coffee stains and brush strokes instead of ink or pencil lines. The paper background should show grain and uneven absorption, giving it an organic, vintage look. Preserve the likeness and proportions of the face, but render with artistic imperfections, splashes, and subtle tonal gradients that mimic coffee painting. Avoid modern digital effects—make it look handcrafted."
