Create a photorealistic, 4K image of a female in a cozy cafe

Create a photorealistic, 4K image of a female in a cozy cafe. She is 18, platinum blonde and has intense blue eyes. She is dressed in a light summer dress and stylish boots. 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, near full body, looking 45 degrees from camera.
