Thiếu nữ kỳ ảo dưới nước sắc xanh

A high-quality 3D CG fantasy illustration of an adult girl submerged in a clear, dreamy underwater world. She has silky, water-blue ultra-long twin tails floating naturally around her, large crystal-clear blue eyes, fair transparent skin, and delicate facial features with slightly parted lips in a faint smile. She wears a light, translucent white ruffled gauze dress with soft pleats across the chest and shoulders, accented by an exquisite blue gemstone necklace. Close-up half-body composition, reaching one hand toward the camera in an engaging, interactive pose. The underwater environment features transparent floating bubbles, surface water caustics, soft ripples, refracted beams of volumetric light, dreamy bokeh, and shallow depth of field. Aesthetic, ethereal, and airy atmosphere dominated by a color palette of lake blue, ice blue, and pure white.
