"Editorial abstract illustration evoking the emotional arc of a song titled "40 Days" by Slowdive. Noticeable climb from quiet to loud. layered composition, overlapping color planes. Mood: dreamy, introspective, melancholy. Visual style: early-1990s alternative aesthetic, weathered film grain. Painterly, grainy film texture, muted palette with strategic accent colors. The composition should read left-to-right like a timeline — calm on one side, intensifying toward the other. Strictly no faces, no text, no logos, no literal objects, no band imagery. Pure color-field abstraction with emotional weight. 16:9 editorial format."
