The other quick sketch to get the feel of the water-soluble oil paints.  I tried a loose wash for a background, just diluting the paint with water.  It makes a lovely wash, with more substance but also more stickiness and drag than paint thinned with spirits.  All in all I love how these paints make me push more.  They're forgiving of indecision too, since they chalk up less than traditional oils when an area is re-worked.
