i would answer but you didnt inculude what the lines say.
O’Keeffe tends to do more abstract versions of natural form and a lot of her paintings consist of bright colours or browns , reds , yellows and shades. She tends to use oil paint . In a lot of her art pieces she paints skulls in the desert , the skulls are painted in a realistic style however she will either place the skull somewhere unusual or have another unusual object beside the skull . There is no particular way that the light is showed apart from where the shading is showing that the light is coming from the opposite angle.
One of the main reasons is because the film is so popular (it was recognized as one of the first colour feature films).
This would make the film a modern staple despite its age.
