This photo is very succesful because it has a lot of unity and the colors work well together tying the yellow in the sky nicely with the yellow on the building. There is also a lot of variety in the colors and shapes. I really like how everything is very proporionate and everything seems to work very well together in this photo.  I think it is trying to convey that there can be excitement in simplicity, by taking a simple photo of a building and making it interesting with colors and shapes it makes this message more clear. This photos owner and name has been lost due to my stupidity.
