Spiral Drawing

Miguel Herranz demonstrated "spiral drawing" in week 5 of "Stretching" in Sketchbook Skool.  He instructed us to find a scene and focus on one thing we found interesting and draw it near the center of the page.  Then instead of working out the entire composition we were to draw in a spiral or circle out from the center to the edges.  I think I must draw complicated scenes like this because this didn't seem strange or different.  I started with the "one way" sign and worked out from there.  This is really not the scene I wanted to draw but was the only thing I could find from a shady spot in the old Cordova neighborhood near my house.  I want to draw some of the older more interesting buildings from the early part to the last century.  But there were so many cars parked everywhere that I couldn't find a place to park myself without sitting in the very hot sun.  The vantage point that I chose was the back of a restaurant (now out of business) that had an interesting pattern of railings, walkways, and great shadows.  I didn't finish the entire scene.  I was satisfied with the incompleteness of the drawing.
