Abstract Cityscape - Single Line Drawing

I love to draw these intricate cityscapes with only a single line... I set the pen on the paper and dont' lift it up until the end, and always try to make the start and the finish visible.  This one took a bit!  It's on heavyweight watercolor paper, and measures SIZE.  It comes unframed, but if you would like me to frame it for you, let me know and I am happy to discuss available options.
