Nano Banana Pro Brand Food Promotion Poster (3)

9:16 aspect ratio, vertical orientation. High-end commercial photography, dark luxurious feel, cinematic quality, hyperrealistic, high detail. Pure black background (#000000), no pedestals, no platforms, no ground, subject and elements all floating in space. The core subject is [User Provided Subject]. Deconstruct the subject into multiple 'identifiable, understandable, hierarchically related components' using your database knowledge and internet search. Determine and design the decomposition logic and hierarchy based on the subject's characteristics. Overall composition uses a 'vertical layered floating structure', forming a clear visual reading path from top to bottom. Clear spatial separation between each layer, connected by air, steam, and light/shadow, not direct contact. The visual center is the main axis, stable yet dynamic composition. At the very top center, a high-end main title floats: AI-generated copy based on the subject (can include Chinese main title + English subtitle). Font style: handwritten calligraphy / natural writing feel. Material: 3D metallic texture, forged gold imitation. Expressive characteristics: heavy, 3D, realistic metal reflections, highlights and shadows. Generate 4-6 logically clear floating layers based on the subject, e.g., Ingredient Layer / Composition Layer / Key Element Layer / Core Structure Layer / Atmosphere or Emotion Layer. Each layer has clear material, color, texture, and volume. Leave air and space between layers, not crowded or stacked. All middle layers: are in slight steam, heat, or air disturbance. Fine particles, mist, water vapor, or dust floating. Controlled by a unified lighting system, maintaining overall consistency. Transition Zone (Important): Deliberately leave a 'significantly larger spatial break' between the subject layers and the final presentation. This area is mainly air, steam, smoke, energy flow, light mist. No solid objects placed. Function: create rhythm, breathing room, and visual contrast. Reinforce the transition 'from structure to finished product / from process to result'. The bottom of the frame presents the complete, final form of the subject: in a 'finished state / peak state / most attractive presentation'. Full texture, rich detail, highly tempting or engaging. Naturally integrated with the background, yet clearly prominent. Continuous steam, smoke, or energy emanates upwards from this area. Moderately add explanatory annotations in the image: bilingual (Chinese/English). Text is restrained and elegant. Use thin lines or arrows to point to corresponding layers. Annotation content is AI-generated based on the subject. Does not steal the spotlight, only serves as 'high-end interpretation'. Bottom right corner: a floating brand signature or signet logo. Style consistent with the main title (calligraphy feel, metallic gold, 3D, etc.). Can be paired with subtle starlight, micro-flash effects, emphasizing a high-end feel. At the bottom, a one-sentence commercial blockbuster slogan for the subject. Lighting system: 45° professional studio lighting. Warm rim light outlines structural edges. Localized highlights emphasize material realism. Steam and smoke are cut by light, forming volumetric light. Overall mood: dark, restrained, expensive, or one side at the bottom (adjustable based on subject). Possesses 'soul / warmth / handcrafted feel / high-end commercial aesthetic'. Suitable for brand posters, key visuals, cover-level commercial displays.
