Paolo told BuzzFeed he studies pictures of the characters in different lighting to get a handle of their facial structure and contours.
He said he uses an eyebrow pencil to alter the appearance of his features, and light and dark cream or stick foundations to contour.
He adds another layer of foundation, and uses neutral, cool-toned eye makeup.
He contours his nose and uses black liner to shape his lips before more contouring and highlighter on the cheekbones, nose, forehead, and chin.
Paolo finishes the look by styling a wig to match the character, and nailing their facial expressions.
Each transformation takes about half a day to complete.
