I recently had the chance to do a painting demonstration for a group. I decided to revisit the image of Mary I previously painted. I started out by drawing out the face, paying particular attention to the divisions between the lights and darks. Click on any of the images for a larger version.
After getting the drawing down, I quickly ink the drawing. Sometimes I use a brush and india ink. In this case, I used a 01 Micron Pen. Be sure that if you use a pen, it is a pigment based pen. If you use something like a sharpie, dye based, it will make a mess of your oil paint, bleeding through.
At this point, I do a complete pass on the painting with raw umber, blocking everything in. Because my lines are inked, I don't lose them, even with some scrubbing of the surface. Now on to color. Forgive the color shifts on the in progress shots. I didn't color balance the in progress shots.
I try to complete the painting in a couple passes, laying in everything fairly rough first, and then the second pass, improving the accuracy and refining my edges.
And the final painting:
