Create a photorealistic, 4K image of a female receptionist in a small modern art

Create a photorealistic, 4K image of a female receptionist in a small modern art gallery. She is 18, platinum blonde and has intense blue eyes. She is dressed in a woman's business suit that is slightly non-traditional with only a slip underneath the jacket. Her appearance looks a lot like a Nordic Emilia Clarke. She always has a wicked smile, like she has something naughty on her mind. The framing should be selfie style, looking 45 degrees from directly in camera.
