Nymph in a Lighthouse: Watercolor Dream

A watercolor painting of a mythical nymph inside a weathered lighthouse. A translucent, graceful figure stands by a wooden railing near a spiraling staircase, her hair like strands of seaweed floating around, skin pale aqua and silver. She wears a gown of sea foam that seems to drift with her. The lighthouse interior glows with warm lantern light, casting golden reflections on damp stone and wooden surfaces. Through the tall window, a wild seascape roars with waves and spray. Use soft watercolor washes, gentle bleeding edges, and subtle granulation to create a dreamlike mood; emphasize mood, light, and motion. Include seashells, barnacles, salt-streaked glass, and hints of mist for atmosphere.
