The man looks disappointed, while the rainbow looks like a crazy mixture of different colors that do not blend at all. The overall effect is disastrous and would make even an experienced painter cringe. The image would be detailed and intricate, with the man's facial features clearly visible, as well as the unevenness of the rainbow paint.",
