Example: Car Timeline Prompt

Elegant minimal timeline illustration showing a three-stage car ownership journey, presented as a sophisticated horizontal progression from left to right against a clean dark background. The sequence shows: BMW 320i Gran Turismo → BMW 650i E64 Convertible → BMW Z4 Roadster → ? (unknown next car).

BACKGROUND:
Solid deep navy-charcoal gradient (#1e2432 at top transitioning subtly to #171c26 at bottom). NO grid lines, NO texture, NO patterns. The background should be completely clean and uncluttered, allowing the car silhouettes to be the sole focus. This solid dark backdrop creates a premium, automotive showroom feeling.

COMPOSITION:
Horizontal layout occupying the middle horizontal band of the frame. Three car silhouettes arranged left to right with generous, equal spacing - approximately 20-25% of frame width between each. All cars sit on the same invisible baseline, roughly centered vertically (around 45% from top). The arrangement should feel balanced and breathable.

SIZE PROGRESSION:
- Car 1 (320i GT): Medium-large, elevated stance
- Car 2 (650i): Largest - long and wide grand tourer
- Car 3 (Z4): Noticeably SMALLER and LOWER - compact sports car

CAR 1 - BMW 320i Gran Turismo:
Side profile facing right. NOT a standard sedan - the GT has a distinctive fastback/liftback profile.

Key characteristics:
- Extended wheelbase
- Raised rear roofline flowing into fastback tail
- Continuous slope to lifted tailgate (not sedan trunk drop-off)
- Four doors with Hofmeister kink at C-pillar
- Higher ride height than standard sedan

Soft silver-white (#e8eaed) solid fill. Subtle window tint (#c5c8cc). Wheels in #b8bcc2. Soft ground shadow (#0d1117 at 30-40%).

CAR 2 - BMW 650i E64 Convertible:
Side profile facing right, soft top DOWN. 2004-2010 6 Series grand touring convertible.

Key characteristics:
- Long, sweeping hood (front-engine V8 GT)
- Large two-door body - significantly larger than a compact roadster
- Open-top profile showing low windshield rake and folded soft top
- Short rear deck with upward kick
- Wider, more muscular stance

LARGEST silhouette of the three. Same color treatments.

CAR 3 - BMW Z4 Roadster:
Side profile facing right, top DOWN. Compact two-seat sports car.

Key characteristics:
- Dramatically long hood relative to tiny cabin
- Very short rear overhang
- Cabin positioned far back toward rear axle
- Low, aggressive stance - LOWER than both previous cars
- "Shark nose" front profile
- Pronounced rear haunches

Visibly MORE COMPACT than 650i. Same color treatments.

CONNECTING ARROWS:
Between each car: thin horizontal line (~2px) with subtle chevron arrowhead.
- Color: Warm gold (#c9a86c)
- Length: ~60-80px
- Vertically aligned with car centers

QUESTION MARK:
After final arrow.
- Size: 80-100px tall
- Color: Warm gold (#c9a86c)
- Style: Clean sans-serif
- Subtle glow: #c9a86c at 8-12% opacity

VISUAL NARRATIVE:
Progression tells story: practical GT → luxury convertible → pure sports car → ???
Size differences and body evolution readable without labels.

MOOD:
Premium, sophisticated, minimal, intriguing. Luxury automotive brand feel.
NOT: Car dealership flyer, blueprint, clip art, children's illustration.

COLOR SUMMARY:
- Background: #1e2432 to #171c26
- Cars: #e8eaed
- Windows: #c5c8cc
- Wheels: #b8bcc2
- Shadows: #0d1117 at 30-40%
- Gold accents: #c9a86c

DIMENSIONS: 1920x1080px

AVOID:
- Grid lines, blueprint elements
- Brand logos or badges
- Excessive detail (door handles, mirrors)
- Same size for all cars
- Pure white (#ffffff)
- Text or labels
- Gradients on car bodies
- 3D perspective
- Photorealistic rendering
- Cartoon/sketch styles
- Busy backgrounds
- Heavy arrows
- Closed roofs on convertibles

Visual Categories

Type	Description

Key Rules

1. Be extremely specific - "BMW 650i E64" not "a car"
2. 500-1500 words per prompt - if shorter, not detailed enough
3. No pixel art, Excalidraw, or blueprints - wrong for 30+ business owners
4. Clean dark background + gold accents - signature style
5. Premium automotive/editorial aesthetic - luxury brand feel
6. Include AVOID section - prevent unwanted elements
7. Text IS allowed - Imagen 3 handles text well. Use short labels (car names, numbers, "VS") not sentences
8. Faces ARE allowed - Imagen 3 generates realistic people/faces. Include in thumbnails and visuals as needed

YouTube Thumbnails

For thumbnails, generate COMPLETE images including:

• Person/face with specified expression and pose
• Text overlay (title, 3 words max)
• Background visual elements
• All composed together in one generation

Do NOT say "face will be composited in editing" - generate the full thumbnail.
