Create a charming watercolor painting of Santa Claus on a clean, white background. Santa should be depicted in his classic red suit with fluffy white trim, painted with soft brushstrokes for a warm and inviting look. Capture his joyful expression, rosy cheeks, and a gentle twinkle in his eyes. The style should be minimalist, focusing on Santa's warm personality and festive spirit, using soft colors and textures to give a cozy, nostalgic feel. --ar 3:4 --v 6.1
