Create a highly detailed 3D render of a Christmas tree star ornament in a dark, whimsical Tim Burton–inspired style. The star is five‑pointed, but slightly crooked and asymmetrical, with long, thin, subtly twisted arms like bony fingers. Its surface combines aged gold metal and matte black, with irregular black‑and‑white stripes and deep purple accents. Use realistic PBR shading, visible edge wear and tiny paint chips. Illuminate it with dramatic, high‑contrast warm key light and a cool rim light, against a blurred, gothic interior background with faint, moody Christmas lights.
