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 ribbon colors. Background contains dense background pattern that continue through parts of the face to create an optical illusion effect.
