Watercolor Siren in a Gothic Cathedral

A watercolor painting of a siren inside a grand Gothic cathedral. The siren sits on a carved stone pedestal in the nave, her upper body human with long flowing hair, and a shimmering tail curling along the marble steps. Use soft wet-on-wet washes in blues, teals, sea-greens, with hints of gold to suggest sunlight. Light filters through stained-glass windows, casting vibrant kaleidoscopic patterns on the damp stone and arches. Seaweed and delicate coral cling to pillars, blending sea and sacred space. The mood is serene, ethereal, and otherworldly, with loose, translucent brushwork and gentle edges characteristic of watercolor. Composition emphasizes soaring arches and a central, luminous siren gazing toward a distant altar, as if summoning tidal whispers.
