Dark fantasy book cover illustration, square composition. A young woman in traditional Romanian folk clothing with a white headscarf, standing at the edge of a dark pine forest at dusk, facing away from viewer toward a distant stone house glowing with faint warm light at the base of jagged black mountain peaks. She holds a single strand of red thread in her hand. Muted color palette — deep blues, blacks, and cold greys, with warm amber light as the only contrast. Atmospheric fog low to the ground. Painterly, moody, cinematic lighting, evocative of Eastern European folklore. No text, no logos.Aspect ratio: 1:1,1400x1400px
