I started this 2 weeks ago, when it was a lot cooler. Today, as the temperature started to climb to 90 degrees, was I sorry to be painting in the sun! Not to mention that in the past two weeks the early irises had faded away. Still, I wanted to get rid of an excessively sweet feeling the initial sketch had and I reversed much of what had been light, putting it in shadow. The result was a great improvement.
