Create a double exposure art piece that features a piano-playing woman's silhouette. Her outline is filled with a pastel-colored lake scene, bathed in the soft glow of midday sun. The area around the silhouette is pure white, but it's riddled with small, carefully placed splashes of color that just slightly extend beyond the silhouette. The composition is soothing, mystical and wonderful, evoking feelings of calm serenity. The piece should present as a detailed matte painting with deep, complementing colors. The intricacy of the design should give it a fantasy-like feel, aiming for 8k resolution, typical of trending content in a digital software environment like Unreal Engine.
