📝 Prompt Weighting Syntax (Leonardo / Stable Diffusion)

Unlike Midjourney, Leonardo uses parenthesis weighting to emphasize keywords:

(keyword:1.2) - Increases importance by 20%
((keyword)) - Increases importance significantly (approx 1.1x per parenthesis)
[keyword] - Decreases importance (negative weighting)

Example: concept art, (cyberpunk warrior:1.3), ((detailed armor:1.2)), [generic]

Mastering Concept Art in Leonardo AI

🎨 Character Sheet Keywords

Add "character concept art sheet, multiple poses, turn-around views, front and back views, expression studies." These signal professional pipeline requirements to Leonardo.

🌍 Environment Scale Indicators

Include scale references: "wide establishing shot, massive scale, tiny figures for scale, epic panoramic view." Leonardo needs scale cues to render appropriately sized environments.

⚙️ Prop Design Specifics

Use "product shot, multiple angles, exploded view, detailed texture, material callouts, industrial design." Technical language pushes Leonardo toward accurate, usable prop designs.

🎭 Mood & Atmosphere First

Start with mood: "moody, atmospheric, dramatic lighting, color palette study." Concept art sells feeling before details. Lighting and color do 80% of the work.

📏 Consistent Framing

Character concepts: 768×1024 (portrait). Environments: 1024×1024 or 1216×832 (wide). Props: 1024×1024 (square). Consistent framing builds professional portfolio cohesion.

🔍 Reference Professional Styles

Add "ArtStation, concept art, production ready, lead designer, senior artist." These keywords signal quality expectations and trigger Leonardo's most professional rendering.
