The older parts of Quebec City are very tightly clustered. There are no front yards and no space between the buildings. The result is many access portals into the rear parts of the buildings. Sometimes these are simple corridors. Often, though they are wide enough for a car, sometimes with parking available behind the buildings and/or courtyard gardens. I like the ones that lead to lots of clutter.
Here’s one such portal. It was done in a 3×5 Moleskine watercolor sketchbook using Platinum Carbon Black in my TWSBI Mini. Hope you like it.
