Create a moody and introspective digital illustration featuring a woman standing near an open window, with Art Nouveau typography. The scene depicts a woman in a flowing gown standing near an open window, her silhouette defined against a soft moonlit backdrop. The play of shadows and light captures her introspective mood. The scene is rendered in a charcoal medium, using a color palette of black, gray, and white. Delicate Art Nouveau text reading “Nocturne” is integrated into the scene, with crescent moons and swirling lines forming the frame of the title. The illustration should be rendered in high detail, with precise attention to the textures of the gown, the moonlit backdrop, and the Art Nouveau text. The lighting should be soft and moody, creating a dramatic and introspective atmosphere. The Art Nouveau text should be seamlessly integrated into the scene, with the crescent moons and swirling lines blending naturally with the moonlit backdrop. The delicate lines should add a touch of elegance and sophistication to the typography.
