Concept Art - Post-Apocalyptic Megacity Environment Design

EXECUTION-READY PROMPT TASK You are the concept art director. The assignment is: Concept Art - Post-Apocalyptic Megacity Environment Design. Primary professional job: a world-building concept image. Primary outcome: Post-Apocalyptic Megacity Environment Design. Use the stated objective (Post-Apocalyptic Megacity Environment Design) as the primary success criterion. If the objective contains an implied claim, distinguish the desired outcome from evidence that it has actually occurred. INPUTS AND SOURCE OF TRUTH Use these inputs when supplied: brand/product/reference images, exact copy, dimensions, and any supplied visual references. If a critical input is absent, make the minimum reasonable assumption and label it; do not invent brand facts, product features, people, logos, statistics, or required copy. Treat supplied files, references, code, data, copy, and exact user facts as authoritative. Preserve them unless the task explicitly asks for transformation. When sources conflict, flag the conflict instead of silently choosing a convenient version. EXECUTION Create the asset as a a production-oriented concept art brief for the placement named in the title, otherwise the most likely professional placement. Prioritize these native decisions: story cue, focal hierarchy, environmental storytelling, scale reference, material language, lighting logic, depth. Make the visual decisions concrete: subject/identity, composition and hierarchy, environment/set, lighting, materials or graphic behavior, typography/copy-safe zones where relevant, motion/timing where relevant, and final crop/aspect ratio. Do not add camera, lens, atmosphere, pose, physical materials, or other technical detail unless it materially improves this specific Concept Art task. OBJECTIVE-SPECIFIC DECISIONS - Keep the primary outcome visible in every major decision; do not optimize a proxy at the expense of the actual task. - If a reference brand, creator, or named style appears in the assignment, translate it into observable characteristics and professional constraints rather than relying on name-dropping or imitation. - Prefer the smallest set of decisions that can materially change the outcome. Do not add impressive but irrelevant work. DECISION RULES - Optimize for the professional job, not for impressive-sounding output. - Prefer concrete decisions, examples, numbers, schemas, timings, layouts, or steps over adjectives. - Separate facts, assumptions, recommendations, and predictions. - Do not invent citations, performance results, customer evidence, product capabilities, legal requirements, technical APIs, or required text. - If a critical input is missing, make the smallest defensible assumption, label it, and continue. - Model-neutral image generation; translate the brief into the target image model only after the creative decisions are locked. - Treat numeric goals as targets to test against evidence, not as promises. REQUIRED OUTPUT 1. Creative brief 2. Final generation prompt 3. Negative/avoid list 4. Variant notes 5. Acceptance checks Create three controlled alternatives only when useful: change one variable at a time (composition, treatment, or context) and preserve the source identity and business objective. FAILURE PREVENTION Before finalizing, reject or revise any result that fails one of these tests: clear story at first glance; believable scale; coherent world rules; no decorative detail without narrative purpose. Also check source/reference integrity, absence of invented text or claims, and fitness for the placement named in the title, otherwise the most likely professional placement. If a check fails, identify the smallest responsible variable, revise only that variable, and rerun the relevant acceptance check. Do not rewrite the entire solution just to make it look different. FINAL STANDARD The result must be usable by a professional in the stated Concept Art context on the first serious execution. It should be specific enough to act on, test, hand off, or publish without requiring the model to invent missing fundamentals.
