Twin Fashion Portrait on Giant Mushroom

Create a surreal high-fashion studio portrait in a vertical 2:3 frame: exactly two identical-looking young men with voluminous curly dark hair sit back-to-back on top of one enormous mushroom. The mushroom has a thick beige stem with natural brown speckles, a broad rounded cap, a tan underside, and a dark blue denim-textured top with visible worn seams and frayed edge detail. Both men are slim, late-teen/young-adult, with light-to-medium skin, serious calm expressions, and both gaze away from each other toward opposite sides of the frame. The left figure wears a dark brown oversized jacket over a charcoal button-up shirt, loose dark brown trousers, and clean white low-top sneakers; his legs hang over the left side of the mushroom cap and his hands rest near his pockets. The right figure wears a black denim jacket over a black T-shirt, loose black trousers, and clean white low-top sneakers; his legs hang over the right side of the mushroom cap and his hands rest near his pockets. Use {argument name="subject identity" default="two identical curly-haired young men"}, {argument name="mushroom cap material" default="dark blue denim fabric"}, {argument name="left outfit color" default="dark brown"}, {argument name="right outfit color" default="black"}, and {argument name="background color" default="moody teal-gray gradient"}. Keep the composition centered and symmetrical, with the mushroom stem rising from the bottom center and the figures occupying the upper-middle area. Lighting should be soft cinematic studio lighting from above/front, with gentle shadows, realistic fabric texture, detailed skin and hair, muted editorial colors, and a minimal foggy teal-gray gradient background. No text, logos, props, or extra people.
