Convert the portrait into a cartoonish caricature where the head is significantly larger than the body, around 60% of the total image. The facial features, especially the eyes, nose, and mouth, are exaggerated in size to create a comical effect, with a slight distortion in the proportions to emphasize the humor. The subject's body remains small and simple, drawing attention to the oversized head. Use bright, vivid colors for a classic cartoon style, with thick black outlines around the features to give it a bold, graphic look. Lighting is soft and even, with a slight glow on the face to highlight the exaggerated features. Photoshop effects: Color Grading to enhance the vibrant tones, Sharpening to emphasize the cartoon outlines, and Frequency Separation to smooth the skin for a polished, cartoonish finish.
