Three-Style Cube Poster

Using the provided reference image as the geometric base, turn the rough hand-drawn nested cube/tunnel form into a polished three-column style exploration poster. Keep the same core structure: an outer cube frame with inward sloping faces leading to a smaller centered cube opening. Create exactly 3 vertical panels separated by white gutters, each showing the same object interpreted in a different visual style, with a caption block underneath each image.

Canvas and layout: Wide horizontal poster, 3 equal columns. Each column has a large square image area on top and a clean white text area below. Use elegant editorial spacing and centered typography.

Panel 1: Render the reference form as a realistic sculptural object made of rough stone or concrete, sitting on a dark reflective surface. Add warm internal lighting along the inner edges and openings so the structure feels physically deep and architectural.

Panel 2: Render the same form as a modern minimalist geometric illustration: clean black outlines, transparent glass-like cube faces, subtle blue and gray planes, white studio background, crisp shadows, and a restrained architectural drawing feel.

Panel 3: Render the same form as a dreamy fantasy art object: a glowing transparent crystalline cube floating in the sky, reflecting sunset clouds, mountains, stars, and cosmic light, with luminous pink-orange-blue highlights.

Text: Add exactly 3 numbered Chinese caption blocks beneath the panels:
1. Title: 1. 写实风; subtitle: “光影与材质，呈现空间的真实感”; small line: “— 看见结构中的深度 —”
2. Title: 2. 现代简约风; subtitle: “简洁的线条与色彩，突出几何美感”; small line: “— 简单的形状，丰富的可能 —”
3. Title: 3. 梦幻艺术风; subtitle: “用光影与想象，赋予空间诗意”; small line: “— 在有限的空间，看到无限的世界 —”

Style constraints: Preserve the reference object’s recognizable nested-cube geometry in all 3 panels. Make the poster clean, premium, and presentation-ready. Do not add extra panels, extra objects, watermarks, logos, or unrelated text.
