Edgar Degas "Waiting"

"Waiting" is a pastel on paper by the French Impressionist Edgar Degas dated between 1880-82. I read online that Edgar Degas was interested in ballerinas so much because of the contrast between their beauty and grace on stage and the reality of the physical and physiological labor that is deceived during that ballerinas performances. After researching this painting supposedly this painting is depicting a ballerina accompanied by her chaperone. I believe the chaperone is sitting there patiently waiting while the ballerina stretches and prepares for her performance. What I like most about this picture is the drastic color difference between the characters. I like how the ballerinas colors are creamy and soft as opposed to the the other woman who's colors are dark.The background is also very vibrant. There is nothing dull about this. Another interesting thing I liked about this piece of work is the perspective. I like how the viewer seems to be positioned above the two women. So the viewers are looking down on the two women. I thought this was an interesting perspective instead of being straightforward.
