"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. 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 hues of red and gold during the soft light of sunset. The aim is to evoke feelings of the melancholy and transience of late summer. No man-made structures should be included, emphasizing the beauty of nature."
