A highly realistic and detailed visual depiction of a tense stand

A highly realistic and detailed visual depiction of a tense stand-off between Lady Vivienne d'Aurelis and Lady Ophelia d'Aurelis at the empire's annual charity event, set in a dieselpunk Imperial European theme. Lady Vivienne is dressed in a luxurious red velvet gown with intricate brass gears and cogs embroidered in gold thread, the train flowing behind her like liquid metal. Her dark hair is styled in an elegant updo adorned with subtle clockwork jewels, and she wears a poised, determined expression. Lady Ophelia is attired in a stunning white pearl-themed gown, with shimmering, iridescent fabric that seems to glow under the event's gas-powered lighting. Her gown is adorned with pearls and silver accents, interspersed with delicate pneumatic tubes, giving her an ethereal and coldly beautiful appearance. Her hair is styled in a sleek, modern twist with chrome accessories, and her expression is confident and calculating. The background showcases the grandeur of the charity event with a dieselpunk twist. Opulent art deco decor is mixed with exposed pipework and brass fittings. Enormous zeppelin-shaped chandeliers hover overhead, powered by visible engines. Guests mingle in the distance, unaware of the silent battle of wills between the two women, their attire a mix of 1920s-inspired fashion and retrofuturistic elements. Servers carry trays of drinks that glow with an otherworldly light, while mechanical orchestras play haunting melodies. The art style is realistic, capturing the elegance, tension, and power dynamics of this pivotal moment, all while immersing the scene in a world where diesel technology and imperial grandeur coexist in a unique blend of past and future.
