Reverse Painting on Glass - My newest medium

I thought for the summer I would try something that I never have before. I am "self taught" in this medium. Not exactly sure how I got into it but I had some small scrap pieces of glass around and was up for a challenge. You start with the detail first and them work backwards. Kind of like monotype (with which I have 15 years of experience). Once you put paint down it is nearly impossible to change it. That is the challenge but the effects amazing. Glossy shinny surface, clear colors and no need to protect the front of it because it is already under glass! Here are a few samples. More images to come.
