A Clockwork Heart Glows Inside an Ornate Velvet-Lined Display Box

Masterpiece. Best quality. Attention-grabbing. Epic. Cinematic. Hyperdetailed. A clockwork heart, intricately designed with gears and springs visible through a translucent casing, beats with a faint, internal light. It is nestled within a velvet-lined, ornate display box, reminiscent of a macabre jewelry case. The background is dark and moody, with subtle gothic horror elements and a painterly texture, captured in a cinematic close-up.
