鐘錶匠將一枚金色齒輪裝進故障的機械夜鶯

An extraordinarily creative, museum-quality steampunk fine-art painting depicting an act of tender kindness inside a cluttered midnight clockmaker's workshop. An aging craftsman wearing multi-lens brass jeweler goggles leans over a dark mahogany workbench, delicately using fine brass tweezers to place a glowing golden crystal heart-gear into the open chest of a broken clockwork mechanical nightingale resting on a velvet cushion. A warm vintage banker's lamp casts focused volumetric light through floating dust motes, highlighting intricate copper springs, ticking gears, and weathered skin textures. Rich metallic physics, deep chiaroscuro atmosphere, museum-quality fine art, 8k resolution, masterpiece.
