OK here are some sketches right out of my books. The line drawing are a lot of fun to do and are done from life. I usually draw like this when i am in a room with a lot of people there is so much going on, so why not draw a little bit of everything.

these are two sketches done in water soluble oil paint. There the first time i used the water oil paints, its was an interesting experience because i just used water as my medium. It was a lot like painting with turpenoid only less tacky and more controllable.
