Describing the characteristics of a cool and artistic girl

The image of a cold, artistic girl, with long straight black hair and bangs, the strands flowing smoothly but slightly messy. Wearing round thin-framed glasses that obscure her gaze, her light gray-white irises present a dull laziness. She is dressed in a loose-fitting white oversized T-shirt featuring a landscape of blue skies, white clouds, ocean, and beach, with handwritten signature text at the hem. Her expression is plain with no upturned corners, and her cheeks are faintly rosy. The half-body portrait is taken from the front with her head slightly tilted. The background is vertically divided into left and right sides by a central axis, with the left depicting a light blue sky and yellow sun symbolizing daytime, and the right a deep blue sky and white crescent moon representing nighttime. The landscape on her shirt seamlessly blends with the background, creating a nested effect of picture within a picture. The lines are clear and flowing with a sketch-like broken line feeling, the blue hue is highly restrained yet rich in layers, conveying a poetic introspective atmosphere of day and night together.
