Create a highly detailed anime character portrait of a young woman named Mai Sak

Create a highly detailed anime character portrait of a young woman named Mai Sakurajima. She has long, straight black hair that reaches down to her waist, with a slightly reddish-brown tint in the light. Her hair is typically worn loose, but sometimes she has it tied in a low ponytail with a ribbon. Her eyes are large, almond-shaped, and a deep, almost bluish-grey color, giving her a calm and serene expression. Her skin is fair and smooth, with no visible blemishes. Mai is of average height, around 5'5" (165 cm), with a slim and elegant build that reflects her background as a model and actress. She is wearing a traditional Japanese high school uniform, which includes a white blouse, a red necktie, and a navy blue pleated skirt that falls just above her knees. She also has a matching navy blue blazer with gold buttons. Mai stands with a graceful and confident posture, and her facial expression is calm, with a subtle, gentle smile. The setting is a typical school hallway with soft lighting that adds a warm glow to her figure.
