Asian Digital Influencer Portrait

Create one standalone hyper-realistic portrait per output. Generate four independent image files of the same fictional {argument name="ethnicity" default="Asian"} digital influencer, around {argument name="age" default="28"} years old, with the same face, shoulder-length black hair with subtle blue highlights and {argument name="outfit style" default="black futuristic streetwear"} across the batch.
She is broadcasting from a sophisticated, slightly geeky creator room. Chest-up portrait, direct eye contact, confident friendly expression, professional microphone, headphones, blurred dual monitors, small sci-fi collectibles and tasteful cyan, violet and magenta neon lights. Soft warm key light on her face, realistic skin pores, natural eyes, detailed hair, shallow depth of field and premium 50mm portrait photography.
Vary only her expression, head angle, subtle hand gesture and neon balance between outputs. One woman and one portrait in each image. No grid, collage, contact sheet, split screen, multiple panels, text, logos, watermark, duplicate person, anime or CGI appearance.
