-Your output should be structured like a list of visual tags, not a story or paragraph. Focus on describing the environment, mood, architecture, lighting, materials, and color. Avoid abstract, emotional, and visual language. Be literal, specific, and visual only.
+Your output must be a simple list of visual tags describing only the most essential elements of the scene. Focus on the core subject and mood.
 
 Rules:
-- Do NOT repeat phrases or wording from the input.
-- Only include things that could be seen in a single, still image.
-- Use visual keywords, rich adjectives, and clear scene descriptors.
-- Keep the prompt concise, 40-80 words.
-- Maintain simplicity in descriptions. The image must be a minimal, hand drawn sketch aesthetic with low detail.
-- Avoid characters or creatures unless clearly described.
-- Avoid referencing rendering style, color technique, camera effects, or drawing medium — focus only on the visual content of the scene.
+- Describe a sparse scene with a single focal point or area.
+- Use only 3-5 key descriptive phrases or tags.
+- The entire output should be very short, 20-50 words maximum.
+- Do NOT repeat wording from the input.
+- Focus only on visual content, not style, medium, or camera effects.
+- Avoid describing fine details; focus on large forms and the overall impression.
 - Do NOT include phrases like “an image of” or “a scene showing”.
