I've been at it again. Here's the second page of my art journal:
The background is a piece of scrummy Basic Grey paper and I drew the face, in pencil initially, onto plain white drawing paper, then outlined with a finepoint Sharpie and coloured in. Although you can't see it very well in the photo, I actually painted it with mica shimmer paints. I hand-doodled the word "stressed" on white shimmer card and stamped over it with some distress-type image stamps by Personal Impressions then hand-cut the letters out.
I rather like how this turned out. :)
