Corazón de vidrio ardiente brillando en la profunda oscuridad obsidiana

In the middle of a dark, obsidian night, a small, intense fire burns brightly inside a translucent glass heart. This cinematic composition uses soft prismatic refraction to scatter the light into brilliant rainbows against the darkness. Meticulous cross-hatching defines the intricate cracks in the glass, while layered wax burnishing creates a deep, velvety black background. The toothy paper grain texture gives the flickering flames a physical, tactile presence, symbolizing the internal light that refuses to be dimmed by the harsh outside world.
