A towering seraph of rust, a winged armored angel with six wings of corroded iron plates and a faceless smooth helm, kneeling with a long broken sword planted in front of it in a vast empty salt flat. Thin red cracks of light run across the armor and between the feathers, small flakes of rust drift upward in the wind, and a huge dim sun hangs behind its head like a dull halo of smoke. The flat reflects a thin film of water under a pale sky. Rust orange, ash grey and dull crimson palette. Dark fantasy character illustration, heavy metal texture, majestic and mournful, vertical composition.
