AI-Style Chosen Concept Art Book Nook

I have been doing a lot of books but the style was mainly chosen by AI or fixed in some way. This Nano Banana prompt lets me choose different styles without changing the whole prompt. <instructions> Input A (story): (e.g., Game of Thrones, Star Wars, Moby Dick) Input B (asthetic): Magma System Instruction: Generate a hyper-realistic, macro 3D render of a "Concept Art Book Nook." Use the following logic to procedurally generate the scene: 1. Narrative Extraction (Input A): Analyze Input A: Identify the Protagonist (The Small Defender) and the Antagonist (The Massive Breacher) from the most iconic scene from the story. Identify the Terrain: Determine the setting (e.g., Castle Wall, Ocean, Desert). 2. Material Synthesis (Input B): CRITICAL: You must translate the Narrative into the Materials of Input B. If Input B is Steampunk: Use Brass, Copper, Gears, Steam, and Leather. The Monster is a clockwork automaton. If Input B is Cyberpunk: Use Chrome, Neon, Carbon Fiber, and Wires. The Monster is a cyborg/mecha. If Input B is Origami: Use Folded Paper, Sharp Creases, and Cardboard. The Monster is a paper sculpture. If Input B is Heavy Metal: Use Iron, Spikes, Chains, and Rust. 3. Container (The Book): The Structure: An L-Shaped open book configuration. The Transformation: The Book itself adapts to Input B. (e.g., Steampunk = A heavy Tome with brass latches; Cyberpunk = A Holographic Datapad; Origami = A Stack of Sketchbook Paper). The Pages: The pages are not flat. They act as the Strata of the terrain, layered and carved to match the material of Input B. 4. Composition: The Antagonist (Vertical): The massive threat bursts out of the Back Cover/Vertical Wall . It is fused with the book, as if the page is birthing the monster. The Protagonist (Horizontal): The tiny hero stands on the Bottom Page/Ground , wielding a weapon appropriate to the style. The Interaction: The Antagonist is looming over the Protagonist. There is a visible connection (fire, slime, wires, laser) connecting the two. 5. Lighting & Atmosphere: Lighting Palette: Derived strictly from Input B. (e.g., Steampunk = Warm Tungsten; Cyberpunk = Pink/Blue Neon; Origami = Soft Studio White). Render Style: Macro Product Photography, 8k Resolution, Shallow Depth of Field focusing on the Hero. Output: ONE image, 1:1 Aspect Ratio, 3D Render, High Material Fidelity. </instructions>
