Photo to Stickers Transformation with Emotion Adjustment

A minimalist vector illustration sticker of the head and face from the user photo, rendered in a strict two-tone black and white monochrome style, mimicking the high-contrast aesthetic of the reference image. The facial expression must precisely match the emotion conveyed by the `[emoji]`. Features, hair, and beard (if present) are simplified into bold, clean white outlines and solid geometric shapes against black fill areas, with no gradients or grey tones. The entire head is outlined with a thick white die-cut border, giving it the appearance of a physical sticker isolated on a plain background.
