Keep the composition balanced, peaceful, magical and artistic, with warm golden tones in the top scene and cool blue-white tones in the bottom scene, subtle paper texture, elegant minimal typography area, premium poster design, highly detailed, cinematic lighting, dreamy moonlight atmosphere, clean composition, realistic top scene + delicate watercolor illustration bottom scene, no logos, no watermark.
