Create a realistic Instagram model with an ethereal yet authentic appearance

Create a realistic Instagram model with an ethereal yet authentic appearance. The model should have a distinctive skin tone that combines rich crimson red with delicate alabaster white, creating a natural but striking contrast. Her hair should be a flowing cascade of deep, vibrant red with subtle highlights and natural texture. Her facial features should be well-defined yet lifelike, with expressive, almond-shaped green eyes that reflect a gentle, natural glow. Her body should have a curvaceous silhouette with prominent, well-defined features, including a large bust. Her complexion should be smooth and even, with no makeup, showcasing a fresh, natural look. The overall appearance should blend fantasy and realism, highlighting a captivating yet authentic beauty ideal for an Instagram profile.
