"Generate a preliminary sketch for a landscape painting that combines the colors

"Generate a preliminary sketch for a landscape painting that combines the colors of Monet, the opulent atmosphere of Klimt, and the delicate style of Kyosuke Chinai, with a watercolor effect. The theme is summer sunflowers. The scene should portray sunflowers in focus with a backdrop of an English garden on a gentle hill, depicted in soft hues of red and gold during the delicate light of sunset. The watercolor should capture the tranquil and ephemeral feelings of late summer. No man-made structures should be included, emphasizing the natural beauty."
