Transform this portrait into a high-end museum-quality artwork using graphite and mixed media. Keep the composition centered with a clean white background. Left side of the face: render entirely in ultra-detailed graphite pencil with soft layered shading and fine crosshatching technique. Right side of the face: reveal through a dramatic vertical torn-paper effect showing realistic color. The eyes should be bright blue with natural skin tones. Add a sky-blue cap worn naturally. The fabric of the cap must transition from color on the right side into graphite shading on the left side. The torn paper edges should curve outward with soft realistic shadows to create depth. Preserve the original facial features and the intense eye contact. Overall style: fine art realism.
