ミニマリスト3Dポートレート、半透明の球体付き

3D-rendered, minimalist portrait of (your character) on a pure black background. Centered composition with a floating translucent monochrome sphere around his head and shoulders; inside the sphere, subtly stacked plate-like layers visible through the glass. Add soft blue and amber glow gradients that rim-light the face and sphere. Keep it balanced, clean, futuristic, with minimal elements, high contrast, and crisp reflections on a glossy surface; shallow depth of field; no extra text, no watermark.
