Create a portrait of a beautiful girl standing in a vibrant flower garden, gazing thoughtfully at a rainy sky. Her long, flowing black hair is adorned with various colorful roses, which contrast beautifully against her fair skin. Her striking blue eyes reflect the soft, diffused light of the overcast sky, adding to the mysterious atmosphere. She wears an elegant dress that flows gently with the breeze, harmonizing with the lush flowers surrounding her. In the background, a beautiful bird flies gracefully, adding a sense of movement and life to the scene. The image should have a shallow depth of field, emphasizing her features while creating a dreamy, ethereal atmosphere.
