I like the space to the left of the painting. It's critical to the photograph.
This is one of those shots I probably would have unthinkingly used rise on the view camera to get -- and thereby lost that important slight tilt. The result would have been a static, failed shot and I never would have been able to figure out why.
Hi Poco: Excellent observation about the perspective. The use of 35mm and the different angles\receeding points caused by the lack of movements really ads to the composition. The assorted angles and the range of tones really help make this image for me.
