A minimalist contemporary avant-garde graphic art poster of a stylized girl with oversized headphones studying in a cafe, inspired by the classic "lofi girl" aesthetic. Minimalist 4-color palette: deep chestnut brown, burnt pumpkin orange, muted matcha green, and warm parchment cream. A sharp geometric abstraction of the girl; her body, clothes, and massive headphones are deconstructed into flat, oversized vector patches and hard-edged blocks. Her silhouette is slender, elongated, and hunched over a desk in a melancholic posture. Her face is a blank panel of the cream. Her headphones are a perfect geometric circle of the green. The environment is a flat puzzle of autumn geometry: books stack into sharp rectangular blocks, and a large window shows abstract falling leaves. Subject and furniture merge into a flat vector pattern against the brown and the orange background. High contrast, solid colors, and a sophisticated, clean risograph grain effect with a subtle chromatic aberration.
