Generate a high-detail image of a slim, human-like mecha with dual elements, representing light and darkness. The mech has a sleek, futuristic design with one side embodying light, featuring shining silver armor with radiant gold and white accents, and an angelic, feathered wing extending from this side. The opposite side embodies darkness, adorned in matte black metal with red or dark purple accents, along with a demonic, bat-like wing. Ensure both wings are equally majestic but distinctly different, capturing the duality theme.
Place the mech in a contrasting background: the light side against a glowing celestial landscape, perhaps with rays of light piercing through clouds, and the dark side against a shadowy, mysterious environment with jagged rocks or a darkened sky. Blend the background at the center to show harmony between the two extremes. Emphasize lighting to bring out the intricate details of both the armor and wings, making the mech look powerful, balanced, and strikingly unique
