Create an image of a vast sunflower field in full bloom under a clear, vibrant sky. In the center of the image, a woman with long black hair, seen from behind, gazes at the landscape, conveying serenity and contemplation. The style of the image is inspired by Van Gogh’s paintings, with expressive brushstrokes and intense colors, especially shades of yellow and blue, evoking the atmosphere and texture characteristic of post-impressionism
