This colorful portrait illustration series by Rizky Irawan features a vibrant, pop-art style with a dynamic use of geometric shapes and bold colors. Each portrait is composed of angular, faceted segments in shades of red, yellow, green, blue, and purple, creating a mosaic-like effect that emphasizes the subjects' facial features with striking contrast. The first portrait highlights a person with red hair, the second showcases someone with glasses and a direct gaze, and the third captures a bearded individual with braces, each exuding a unique personality through the vivid color palette and sharp, modern design. The overall effect is energetic and contemporary, blending digital art with a playful, expressive vibe.
