It is wearing a tattered, black cloak, covered in dirt and dust. The mine is dimly lit, with streams of light filtering through narrow cracks in the rocky walls. The demon is holding a pickaxe, its muscular arms covered in soot and grime. The atmosphere is filled with a sense of danger and eerie silence. The demon's presence is highlighted by a haunting, supernatural glow, illuminating the surroundings. The colors are predominantly dark and desaturated, with occasional bursts of vibrant red and orange from the glowing rocks.
