Today I have been experimenting with painting technique tests for the finish on the Sephilina pin up for Jamie's book.
I want to use the watercolor techniques I've often used in the past, but also preserve the line work. After several unsatisfying experiments, I decided to use gouache with smoothly modeled soft finish rather than a loose watercolor style.
The first thing I did here was draw out a little sample with tuscan red pencil, fleshing out the shadow pattern (which I took liberties with) and added some lines. Next, I applied Golden Acrylic Fluid Matte Medium in a thin layer.
After that, I painted in the local color of the face and hair, very thinly, in gouache, and then began building up layers in the shadows, preserving the white of the illustration board as much as possible. I did find I needed to glaze a little white gouache over some areas and used it for a soft highlight here and there.
After all of that, I used my all time favorite pencil, a brown Stabilo Aquarelle pencil, to add a few lines on top of the color.
