A contemporary mixed media portrait illustration combining expressive, hand-drawn sketch lines with bold color blocking. Visible, imperfect, loose, faint pencil and ink lines layered beneath angular brushstrokes and faceted planes of paint. The color palette is understated and subdued, dominated by [warm browns, ochres, soft grays and desaturated skin tones]. The surface texture is raw and tactile, resembling artwork on [rough paper or cardboard]. Subtle, natural lighting emphasizing facial structure over polished finish. The background shows raw brown cardboard with an unfinished, gestural fade at the bottom. An intimate, honest, and emotionally grounded aesthetic balancing realism with abstraction.
