Abstract Paintings

I have painted abstract paintings in the past mainly as experimental studies. I recently had a friend of my wife's visited from Florida. She is a very talented painter and wood sculpture artist. She noticed a small abstract painting of mine and wanted to buy it. I was flattered by her praise and agreed to exchange the painting for one of her wood sculptures. I may have gotten the better of the deal but it encouraged me to paint abstractly which I believe can help in my realistic painting. 

Below my most recent efforts. I have also began using cold wax medium in all my oil paintings.
