A monochromatic illustration depicting a lone figure sitting against a curved wall in an unsettling, surreal corridor. The scene is rendered using intricate cross-hatching to create a sense of depth, texture, and light contrasts. The figure should have simplified proportions with an eerie silhouette, their expression neutral and devoid of emotion. The corridor's geometric tiles and walls are meticulously detailed with fine linework, emphasizing the skewed perspective and unusual architecture. The empty space around the figure adds a sense of void and isolation. Include symbolic motifs such as a small black bird perched on the curved wall, subtly hinting at an air of melancholy and foreboding. The overall mood should evoke a feeling of detachment and quiet unease, characteristic of Edward Gorey’s hauntingly beautiful illustrations.
