The colors of the acrylic paints are so wonderfully bright and yet you can get these really soft effects with the spray application. I used a lot more colors in this one to create the softer petals that frame the brighter ones. Irises are a great subject because they are so complicated and have such beautiful, scrolling, ruffled petals. The challenge for me is not to overwork the piece as I always want to get in there and describe every detail. I let this one sit for a few days and decided to move on. I will probably do other versions to explore some different painting techniques.
