Академический портрет в смешанной технике

An academic mixed-media portrait illustration faithful to the reference photo, maintaining the exact likeness, pose, and facial expression of the subject. Rendered on a [textured oil canvas] base, combining classic charcoal realism, expressive cross-hatching, and luminous oil painting modeling with bright, realistic skin tones and deep skin texture. The composition is layered with fine academic sketch marks, proportion and measurement lines, delicate ink sketches, and observational drawing studies. Color palette features warm earth tones, rich sepia graphite shadows, and [soft, delicate oil pastel strokes] that match the subject, set against a dark sepia and charcoal background with subtle pencil line washes. Museum-quality editorial fine art presentation with elegant negative space and atmospheric depth. No digital plastic sheen, glossy 3D CGI, cartoon styling, or text.
