This is the grand staircase at Winterthur http://www.winterthur.org/about/period_tours.asp?part=7. I broke the rules of watercolor technique to make these. I used the paint to build up, which is different from how most artists use watercolor. I mixed the paint with just a little water, keeping it thick like a gauche.

These took a long time to paint. I worked on the three paintings simultaneously. I took the source photos using my Canon EOS Digital Rebel SLR. The source photos are shown here. What do you think?
