Cubist Contour Portrait

Transform the uploaded portrait into a masterpiece combining optical contour-line illustration and modern geometric cubism. Preserve the exact facial identity, glasses, hairstyle, age, skin tone, and facial proportions of the original person. Build the face from hundreds of flowing vertical contour lines that bend naturally around the eyes, nose, cheeks, lips, ears, and chin. Merge these contour lines with layered polygonal planes and faceted geometric surfaces inspired by contemporary cubist sculpture. Surround the portrait with large curved geometric ribbons in {argument name="ribbon colors" default="navy blue, teal, ochre, amber, terracotta, and cream"}. Background contains dense {argument name="background pattern" default="vertical black-and-cream stripes"} that continue through parts of the face to create an optical illusion effect. Skin rendered using warm sandstone and ivory tones with subtle engraved textures. Clothing simplified into elegant angular geometric shapes with deep blue gradients. Fine line engraving visible across all surfaces. Sophisticated museum artwork, high detail, premium gallery illustration, dimensional shading, sculptural appearance, realistic likeness, symmetrical composition, portrait centered, 4:6 aspect ratio, masterpiece quality, 8k resolution.
