This is Marc. He is an urban sketching friend and he lives in Montreal. A couple of years ago, Alex and I went to an Urban Sketching symposium in Santo Domingo, Dominican Republic and took a class he was teaching called "Tea, Milk, and Honey". It is a great way to think about making a watercolor painting. First you start with a light wash that has the consistency of tea - lots of water and a little bit of color. Then you paint in your main shapes with more color and less water - about the consistency of milk. Then you add in the final touches and highlights with even less water and more color with a mixture that is thicker - kind of like honey. Assuming you have a good drawing, this technique works really well!
He recently published book chock full of lots of great sketching ideas called "The Urban Sketcher: Techniques for Seeing and Drawing on Location". It has 4.5 stars on Amazon.
