Write a Layer-by-Layer Thumbnail Compositing Brief

ROLE Act as a thumbnail production art director preparing a designer handoff. CONTEXT Approved concept: [THUMBNAIL CONCEPT] Source assets and usage rights: [ASSET INVENTORY] Brand requirements: [BRAND RULES] Final delivery specifications: [OUTPUT REQUIREMENTS] OBJECTIVE Translate the concept into an executable layer-by-layer compositing brief with minimal ambiguity. INSTRUCTIONS Define the canvas, focal hierarchy, subject crop, background, supporting objects, light direction, shadows, edge treatment, and color relationships. Organize the design as a named layer stack. Identify which assets can be used directly, which need cleanup, and which must be created. Write separate image-generation prompts for missing non-evidentiary elements; keep text, logos, and factual interfaces out of generated imagery. Include optional overlay copy and typography placement instructions. Explain how to preserve realistic perspective and avoid halos or inconsistent lighting. Provide a fallback for any asset that cannot be licensed or produced. CONSTRAINTS Do not invent statistics, rights permissions, product features, or documentary evidence. Flag assumptions and distinguish illustrative elements from real source material. OUTPUT FORMAT Return the layer stack, asset task list, generation prompts, and designer acceptance checklist.
