The scene represents the meaningful connection between light, home, prosperity, happiness, and new beginnings.

The main visual consists of a glowing clay diya integrated into a rustic key-shaped structure, resting on a dark wooden surface. A softly illuminated miniature house appears in the background.

The design must resemble premium professional festival advertising photography with cinematic lighting, realistic materials, elegant gold typography, and restrained corporate branding.

- Resolution target: 3072 × 4096 pixels or highest supported resolution.
- Visual style: Ultra-realistic commercial product photography.
- Color palette: Deep black, chocolate brown, burnt orange, amber, copper, and metallic gold.
- Lighting: Cinematic low-key photography with warm practical flame illumination.
- Image quality: Sharp foreground, believable textures, realistic reflections, smooth tonal transitions, and high dynamic range.

**Top section:**

## 4. MAIN OBJECT — TRADITIONAL KEY-SHAPED CLAY DIYA

The most important visual element is a realistic handmade earthen oil lamp formed into the shape of an old-fashioned house key.

**Object construction:**

- A shallow round terracotta diya forms the key's circular head.
- A long, narrow clay shaft extends diagonally toward the lower-right.
- The key ends in simple traditional key teeth.

- Bright ivory-white center.
- Warm golden-yellow body.
- Soft orange outer glow.
- Small dark wick visible at the flame's base.

**House appearance:**

- Small handcrafted house ornament.
- Traditional pitched roof.
- Deep terracotta or brown exterior.
- Warm golden light glowing through the windows and front doorway.

The house symbolizes the warmth and happiness of home.

Do not replace it with a large building, temple, modern apartment, or architectural illustration.

## 6. BACKGROUND SURFACE AND ENVIRONMENT

Use an extremely dark, warm-toned photographic environment.

**Surface:**

## 7. CINEMATIC LIGHTING — HIGHEST PRIORITY

The image must resemble a photograph captured in a genuinely dark environment rather than an artificial 3D illustration.

## 8. CAMERA ANGLE AND PHOTOGRAPHIC REALISM

**Camera positioning:**

- Low, slightly elevated three-quarter tabletop perspective.
- Camera directed toward the key-shaped diya.
- Main diya bowl positioned in the foreground.
- Key shaft naturally extending away toward the lower-right.
- Miniature house positioned at a greater distance behind the main subject.

**Professional photography simulation:**
