Hyper-realistic oil painting on canvas, thick impasto, rich oil texture, visible brushstrokes, canvas grain, night scene, dramatic chiaroscuro, soft moonlight piercing through mist. A young rusalka (water spirit) sits in the shallow water of a dark forest river, her pale skin almost translucent, glowing faintly with an unearthly light, covered in water droplets that sparkle like pearls. Her long wet hair is silky, flowing, intertwined with white water lilies and tiny river flowers. Her eyes are deep, luminous, full of mystery and sorrow. Her body is slender, delicate, tiny breasts, flat stomach with a defined navel, torso above water, the rest dissolving into the dark river. She looks directly at the viewer with a calm, hypnotic gaze, lips slightly parted, as if about to speak. Moonlight reflects on the water, fireflies hover above the surface, dark oak trees frame the background. Deep shadows, strong contrast, masterful light and shadow. Highly detailed skin, visible pores, fine vellus hairs, water droplets, intricate floral details. Painting style influenced by Greg Rutkowski (fantasy realism, epic composition, intricate detail) and Ilya Repin (Russian realism, powerful emotional depth, dramatic light and shadow, masterful oil technique). Fine art, 8K, no retouching.
