And of course, because of that, I get this great idea for a technique experiment. I did a loose pencil sketch, inked it very sloppily with a black brush pen (PITT acrylic, if you haven't been using them, go buy them NOW NOW NOW, they are wonderful things) and then laid increasingly thick washes of acrylic and layers of colored pencil on top of that. At the end, I cleaned up the lines with the brush pen again (the glory of this pen is how beautifully it will cover acrylic paint or anything else) and was really rather surprised at how well it came out. I can see using this technique in the future.
And now, back to the Ox.
