My friend Karel (a.k.a. Charlie) from Iceland asked me to make a caricature of him.
This is the final one (above) done completely in gouache.
This was the first attempt, it made all my friends laugh (very important) but I didn't think I got the likeness just right. This also had a variety of media, it was markers, watercolor, ink, color pencil, and a teensy-weensy bit of white acrylic.
