I now know why I've never attempted buildings...getting the right perspective can be a bear. I guess that's why January will be the month of buildings.
Seattle Woolworth building using FC black pen on Canson journal page. I dropped ultramarine blue, winsor red, and pale yellow on the paper before I even started the drawing. I poured water over the clean sheet of journal page, dropped the 3 colors and then took a paper towel to soak up any excess paint. I allowed the paper to dry for about an hour before I attempted to sketch.
