A magnificent steampunk stag beetle, its carapace meticulously crafted from polished brass and aged copper, featuring intricate clockwork gears visible through small glass panels. Its powerful mandibles are articulated with tiny pistons, shimmering in deep bronze and iron, while delicate filigree wings, made of fine etched metal and stained glass, are folded neatly on its back. The insect exhibits a rich, burnished metallic sheen with subtle oxidation, giving it a weathered yet majestic texture.
