I have been sketching a cool old Portland building in the process of being demolished. After doing two (170828, 170830). Today I drove downtown for a third sketch (170904). I found it difficult to vary the color in the building, maybe because the open spread was 8.5x11? The light was flat, so I did not see much of a distinction between the sides of the building. I think I made a mess of the "demo-ed" part on the top right.
