Cerberus in the Steam Engine: Watercolor Dream

A watercolor illustration of a three-headed Cerberus inside a vintage steam locomotive's boiler room. The Cerberus's three heads rise above the coal-fired furnace, fangs bared and eyes glowing. Steam curls around brass pipes, riveted steel panels, and ticking gears. The scene uses soft washes of blue-gray and sepia with warm amber light from the fire, creating bleeding edges and a delicate paper texture. The composition blends mythic menace with industrial nostalgia, the beast calmly in control of the rumbling engine.
