Apply smooth brush strokes, pastel and warm tones, gentle gradients, clean outlines, and a calm romantic storybook feel. Preserve the face, identity, expression, skin tone, and proportions exactly with zero change. Crop the composition into a perfect circular (round) profile picture, center the face naturally, and softly blend or blur the background to match the painted style. The final output should look like a professionally illustrated round DP created by the same artist.",
