While in Natick, Mass. I took my Honda to Bernardi Honda on Route 9 for regular maintenance. I sat in their well-maintained, WiFi equipped waiting area while they did the work on my car. I had the iPad and after checking my thrilling (not) e-mails I did this drawing of the door and front windows of the Honda showroom. It was a grey day so there wasn't much contrast or color. You can see parked cars as sketchy black and white areas with red tail lights. As I was waiting and drawing, people were putting up blue, white, and silver-colored balloons (visible at upper right) for a marketing event.
Honda drawing is Autodesk Sketchbook Pro, original image about 8" x 6".
