Create a high fantasy digital art masterpiece painting featuring Guardian, the divine protector of daily life. The character should be the central focus, depicted with a glowing, protective shield as a symbol of safety. Guardian should exude a mystical and serene aura, standing tall and vigilant. The scene should be ultra-detailed and rendered in ultra-high definition (8K resolution) with 3D shading, superior quality, and complex design. The illustration should have subtle luminous highlights and rich, but not overly vibrant colors, to emphasize a sense of calm and protection. Use high contrast and ensure it looks like a cover illustration of the highest quality. Guardian is shown prominently, ensuring safety in everyday life and protecting against daily dangers. The aspect ratio should be 1147:2048. --s 750 --style raw --ar 1147:2048 --niji 6
