A while back, I won three tubes of Daniel Smith Water Soluble Oil Colors (in primary colors) via a Dick Blick Holiday Sweepstakes.
I finally decided to experiment with the tubes. I hadn't worked with oil paints in quite a few years. On the first day I really enjoyed working with the oils. By the second day, the paints proved to be more of a challenge.
I was surprised to find out that water soluble oil paints do not dry faster than traditional oil colors.
Then my use of graphite began to mess things up. Some mixed media artists love the grungy look that graphite produces in a painting. Others steer clear of that medium. I think I may use less graphite in the future. I still need to rework the lip area in the painting.
