Fantasy Cuckoo Clock With a Mechanical Dragon

"An enormous, ornate wall-mounted cuckoo clock made of dark petrified wood in an eccentric collector's study. The clock face is a large, glowing amber glass dragon eye with gold Roman numerals and sharp metal claw hands. The pendulum has the shape of a long, spiky dragon tail. At the top of the clock, a set of iron gates has burst open and a small mechanical dragon made of oxidized copper and leather has emerged, breathing a jet of blue flame and thick grey smoke. Atmospheric lighting, embers from a nearby fireplace, dusty books and maps in the background, highly detailed, cinematic, 8k resolution."
