Graphite Pencil Field Sketch of Amy Winehouse

UHD 8K, vertical 9:16. Ultra-detailed close-up graphite pencil field sketch of Amy Winehouse, instantly recognizable iconic beehive hairstyle, dramatic winged eyeliner, calm introspective expression, tight portrait framing. Minimalist line-and-shadow drawing with bold contour lines, expressive cross-hatching, loose hand-drawn strokes, visible construction lines, subtle smudges, erasures and imperfect pencil marks. Raw observational field-notebook aesthetic on aged yellowed paper, delicate stains, creases, faded graphite and pronounced paper grain. Authentic handmade character, natural tonal variation, sophisticated artistic composition. Monochrome graphite only, no color, no ink, no digital effects, no modern elements. Signature “by Slow” subtly integrated bottom right.
