((master piece)) Anime-style illustration, high-quality, 8k, concept art, divided into parts, inspired by Makoto Shinkai, crisp image, digital painting, trending on ArtStation and Pixiv. The scene has a low-angle perspective, showing two humanoids in full view, separated by a celestial blue energy, positioned at the center of the illustration. The background features a contrasting setting with a closed-sky sunset on the right and a starry night sky on the left, with natural lighting enhancing the ambiance. Both characters have identical appearances: red-gold eyes, curly black hair with green bangs reaching their eyes. The adult, a Fallen Angel with an athletic build, stands upright with a slight arch in his back, arms by his side, looking up at the sky with a blank expression. He wears tight-fitting martial arts robes made of fine black fabric with golden lines, designed with an opening on the back to accommodate his large, detailed wings with dazzling dark feathers. He also wears earrings. The boy, a Mage with a slender build, is in a dynamic pose, right arm raised towards the sky, with a radiant white sphere of sacred energy spinning in his hand, while purple magic glows intensely along his arm. His expression is severe, with furrowed brows showing deep concentration. He wears loose-fitting, cold-weather clothes: black pants with white stripes, a golden shirt, a black jacket with a zipper, and a gray sweater, along with a necklace featuring a blue sapphire. A floating illusory pentagram appears behind him, glowing with symbols of light and darkness.
