I normally drawing folks on the BART during my daily commute. Today I decided to add color to one of my drawings. I drew the two ladies that were sitting in front of me (I'm not completely sure if they knew) with the intentions of painting the image when I got to the house. After I finished a loose drawing I photographed them with my phone. I would post the photo but I think that would be invading.
I started out with an underpainting of Phthalo Blue (green shade). I used Liquitex Slow Dri Blending Medium... it helps when glazing and also gives you a bit longer drying time. I did this in a Moleskine 5” x 8 ¼” sketchbook. Took about an hour or so.
