The painting Il Colosso...Roma was taken from a photograph I took while in Rome. I only had six hours so I selected the colosseum as the one site I wanted to visit. The painting is based on a drawing done from the photograph with color added in water based oil paint. The final touch to the design was the addition of a glaze of transparent red in oil paint. The painting was developed in several glazes with a final glaze of liquin by Winsor and Newton, try it, it produces a very effective glaze over your painting.
