"A bouquet of vibrant yellow flowers, including sunflowers, displayed against a solid red background (no gradient). The flowers should have detailed petals with realistic textures, highlighting the brightness and softness of the yellow tones. The green leaves should be well-defined, complementing the flowers. The red background should be vibrant and intense, creating a dramatic contrast with the flowers, but without light elements, such as flares or exaggerated lighting effects." --s 750
