AI Prompt for Japanese Horror Novel Cover Art

"A dark psychological horror novel cover illustration in a cinematic, gritty digital-painting style. Create a wide, ominous composite scene set in a decaying modern Japanese environment, blending a commuter train interior on the left and a late-night office on the right, with a ghostly female figure standing in the exact center foreground, shown from behind. Her long dark hair is messy and damp-looking, and her face is completely obscured by a solid black rectangular void. The palette is cold blue-gray, charcoal, dirty white, and desaturated brown, with harsh fluorescent overhead lighting and deep shadow. On the left side, show the inside of a crowded train car with 4 visible commuters: 2 standing men in business suits holding or standing beneath hanging straps, 1 seated woman in muted officewear with her face blurred or obscured, and 1 more distant passenger near the door. Include a row of hanging hand straps above them, grimy metal poles, scratched windows, and a claustrophobic perspective. In the bottom left foreground, place 1 large cracked white flowerpot containing 1 dead, withered plant with curled brown leaves and dry soil. In the center, use the female apparition as a dividing figure between the two spaces; her body and hair merge into black stains and shadow. On the right side, depict a bleak office with 3 visible workers at desks in the background under fluorescent lights, computer monitors, papers, and glass partitions. In the right foreground, show 1 cropped salaryman from chest to thigh, wearing a wrinkled white shirt and loosened dark tie, holding papers at his side; his head is cut off by the top frame, adding unease. Spread black cracks, grime, ink-like tendrils, and water-stain textures across walls, floor, and image borders so the whole scene feels infected or haunted. Add subtle motionless dread, like a cursed presence hiding in everyday life. Overlay large distressed white Japanese title text across the middle: {argument name="title text" default="隙間、そのもの"}. Beneath it, add smaller white subtitle text: {argument name="subtitle text" default="第１日：月曜日"}. Use eroded, cracked, horror-style typography with rough edges, centered over the figure. The overall result should feel like a disturbing literary cover or promotional key art for a terrifying Japanese urban horror story."
