Webcam photobooth grid portrait

Create a low-resolution vertical webcam photo in a 3x1 grid with a 3:4 aspect ratio using the character in the picture. The photo should fill the canvas without borders with photobooth vibe. The screen light is warm and dim, with a grainy/noisy style and a simple, cozy bedroom background. First grid: Exaggerated pout, finger near the lips, black off-shoulder top
