Create a hauntingly beautiful portrait of a woman with an enigmatic expression, set against a soft, muted background that evokes a sense of mystery. Use a mix of digital painting and traditional media, such as charcoal and pastels, to achieve a dreamy, ethereal quality. The face should be the focal point, with delicate, expressive features and an intricate hairstyle that adds to the overall mystique. The color palette should be predominantly muted, with shades of blue, grey, and mauve, and subtle texture overlays to give the image a tactile feel. Utilize a high-end graphics tablet, such as a Wacom Cintiq, to create intricate details and expressive brushstrokes. In Photoshop, apply a subtle Orton effect, combined with a soft focus and a hint of grain, to enhance the image's atmospheric quality.
