What drew me in to the Edward Hopper painting, Cape Cod Afternoon, was the light and the shadows cast by the home. The moment seemed very specific, like Hopper decided to freeze the moment in a very exact time of day. It is so particular, that it places you in the scene, looking off on the house. The perspective that he chose is not one that is head on- we are looking off from an angled side of the house. It makes the house look a bit eerie and lonely, not one that I would actually want to approach. After looking at this painting for a while, I began to nice the difference in the far half of the house from the close half of the house. The closer half is darker, it seems to be forgotten and falling apart. It is empty and dark on the inside, and feels very remote form the viewer. 

Thoughts on Edward Hopper, Post context research:

It was interesting to read about whom Edward Hopper was most influenced by: Edward Degas and Edourd Manet. I would not have put these artists together myself, but further reading said that Hopper was influenced by their depictions of urban life during their time (19th century). Hopper, too, liked to paint modern urban and suburban life. 
It is said that his work of art, House by the Railroad, is most representative of his style: "clearly outlined forms in strongly defined lighting, a cropped composition with an almost "cinematic" viewpoint, and a mood of eerie stillness." You can easily see the similarities in House by the Railroad and the work that I viewed, Cape Cod Afternoon. I think that a lot of this I had noticed, without pinpointed it as especially Hopper-esque. I had recognized the importance of the light in his work to create a specific time and therefore a specific mood. The house does seem very lonely and desolate, definitely not warm and welcoming.
Realizing that these are common themes in Hopper's work and looking at all of his works together, helps explain various aspects of the painting. For example, the emptiness of the house and the dark windows that show that no one is home is common in his paintings. If he does paint people, they are alone or isolated- for example a woman walking alone, or a semi-deserted movie theatre. 
His paintings work together like a movie to evoke the loneliness, albeit beauty, of modern urban times, even while standing in a crowded museum.
