Bold Pop Art Halftone Portrait Variation

Please convert this illustration in a simple and bold pop art style. Based on vibrant color fields, arrange medium to coarse halftone dots (benday dots) in a gradient across the whole, varying density and size by area to create depth and rhythm. However, minimize halftones on the face and skin areas, keeping them as nearly smooth color fields for a natural and clean look. Apply coarse dots strongly to hair, clothing, and accessories to evoke a powerful print feel. Maintain the original composition and characters completely, but change the color scheme boldly.
