Sometimes when you're strapped for time, but have your sketching stuff and golden hour is hitting the Flatiron Building juuuuust right, you have to stop and sketch it. It's basically a law. You may have noticed, it's one of my favorite things to paint in Manhattan (see "related posts").
I realized very early on I didn't have my pencil with me, so I had to go direct to watercolor which I appreciate as a challenge but in actual practice really don't care for. Here it worked out since I wanted to be quick anyway, so I went for a more illustrative style than my usual. I also just ignored the sky and left it to the buildings.
