Dark Steampunk Plague Alchemist Portrait AI Image Prompt

Create a full-body dark fantasy steampunk character concept art portrait of {argument name="character name" default="a plague alchemist wanderer"} standing front-facing in a neutral A-pose on a clean white background. The figure is bulky and intimidating, wearing a rusted bronze riveted gas mask helmet with two glowing toxic green round goggles, a central respirator, and a long segmented breathing hose hanging down from the mask; add two thick ribbed tubes looping from the shoulders and backpack area around both sides of the head. Show faint sickly green vapor leaking from the mask vents. Dress the character in layered ragged scavenger clothing: a tattered dark brown hooded under-robe, shredded tan-and-olive featherlike shoulder mantle, long torn patchwork coat panels, leather straps, buckles, pouches, belts, metal plates, stitches, rivets, and grime. Arms are extended slightly downward with green-gloved or mutated clawlike hands; forearms wrapped in olive green armor and dirty bandages. Include exactly 7 prominent accessory clusters: one broad leather belt with square brass buckle, one diagonal chest strap with vials and tools, one left hip pouch holding glowing green test tubes, one small right hip green vial pouch, one large hanging cage lantern on the right side filled with bright toxic green liquid, one sheathed dagger or tool on the front-left skirt, and two heavy strapped boots wrapped in dirty cloth. Use a palette of rusty browns, tarnished brass, blackened leather, muddy tan cloth, olive green stains, and luminous neon green alchemical fluid. Render in highly detailed ink-and-watercolor fantasy concept art style with sharp black outlines, crosshatching, gritty texture, asymmetrical torn fabric edges, many tiny bolts and scratches, dramatic but even studio lighting, no environment, no text, no watermark.
