Young woman in black dress by cryptic cavern water

A soft, flowing watercolor painting depicting a 20yo beautiful Caucasian woman, her form rendered in soft, fading strokes, almost blending into a background wash of warm diffuse cavern light and wet dark moss green. She stands at right of center at the edge of still water in a vast cavern, clothed in a simple black dress, her gaze directed into the dark submerged crypt entrance before her. The words 'Beneath the Unlit Sea' are painted in a quiet, water-blurred script across the upper left.
