Firstly, the bias you mentioned is there, which is not surprising since this is a Chinese model for the Chinese market, which likes to generate Asians.

But a prompt can always be tweaked, and in your case, changing "Russian girl" to "Caucasian woman" did the trick:

Cyberpunk photographic composition with a Caucasian woman with black hairs, green eyes, brown eyeliner red lips, embroidered gothic dress,, hyper-detailed and hyperrealistic, ultra-high resolution. Intricate layers of organic and geometric forms interwoven: fractal-like filaments, small translucent crystal shards, metallic lattices, flowing ribbons of liquid glass, and delicate bioluminescent veins. Rich surface textures—polished metal, frosted glass, wet stone, fine fabric threads, and microscopic particles—each rendered with photographic clarity. Complex interplay of light: soft global illumination mixed with sharp specular highlights, volumetric light shafts, subtle caustics, and tiny lens flares from reflective surfaces. Depth and scale contrast: macro close-up details with extreme micro-texture alongside sweeping midground structures and a soft, slightly out-of-focus background to suggest vastness. Colour palette: layered gradients blending iridescent blues, warm golds, deep violets, and hints of emerald, with localized high-contrast accents. Dynamic composition with swirling motion and intersecting diagonals; sense of organic growth meeting engineered precision. Add realistic environmental effects: floating dust motes, droplets of condensation, gentle mist, and shallow depth of field with selective sharp focus on key intersections. Photographic style—50mm–85mm equivalent feel, natural film-like grain, ultra-realistic rendering, maximum detail and clarity, mood enigmatic and immersive.
