Cinematic live-action creature design. A monster of the Ash Swarm: a towering humanoid-beast made of half-molten metal and cooling slag, glowing orange cracks across its body, ash and smoke pouring from it, jagged blade-like limbs, faceless head with a furnace-like glowing maw. Ruined gothic cathedral corridor behind, falling embers, dim red light. Grimdark sci-fi horror, photorealistic, film still, original design, not insectoid.
