Split Sketch Photo

I'm attaching a reference photo of a person's face.  Create a portrait illustration in the following exact style,  preserving the subject's facial identity and likeness completely: STYLE: Split-medium portrait — the LEFT half of the face, neck,  and clothing rendered in expressive colored pencil / soft pastel  sketch style; the RIGHT half remains as a realistic photographic  rendering. The boundary between the two halves blends organically  with no hard edge — it dissolves naturally, especially at the  hairline and jawline. MEDIUM SIMULATION (left side): - Loose, directional pencil/pastel strokes that follow facial    anatomy contours (not random) - Color palette: cobalt blue, magenta/hot pink, lemon yellow,    and white — layered and overlapping, replacing realistic skin    tones as shadow/highlight - Strokes are visible and expressive, NOT blended smooth - Hair rendered with blue-dominant multicolor strokes over    dark base - Clothing (if visible) rendered with loose pink/red crayon    strokes diagonally applied MEDIUM SIMULATION (right side): - Clean, sharp photographic realism - Natural skin tones, precise hair detail, soft studio lighting - Retain the subject's exact facial features, bone structure,    eyes, nose, lips with full fidelity BACKGROUND: Flat, matte warm light gray (#D4CFC9 range).  No texture, no gradient. Neutral and minimal. LIGHTING: Soft frontal-slightly-left studio light.  No dramatic shadows. COMPOSITION: 3/4 angle portrait (face turned slightly left),  cropped from upper chest to top of head, centered slightly  left of frame. Vertical/portrait orientation. CONSISTENCY REQUIREMENT: The split must always be a  left-illustrated / right-photographic vertical divide  through the center of the face. The artistic strokes  must always use the same three-color palette  (blue, pink, yellow) regardless of who the subject is. Preserve the attached person's face with 100% likeness  fidelity. Do not alter, idealize, or stylize their  facial features on the realistic (right) side.
