Teenage girl posed in a dimly lit room, lighting only from a nearby window, standing with one leg crossed over the other in a fitting studio pose, wearing a faded grey sweater that has become loose with age, and a knee-length plaid skirt with a high waist and slight frill on the hem, features reflected in the screen of her smartphone which she holds in her hand, long curly dark hair cascading down her back like a waterfall, soft skin and gentle expression on a background of slight blur and subtle brightness ramp on an 8k resolution digital canvas.
