The Retiro Rose Garden, la Rosalera. Posted on November 29, 2017 by victoria A. Olson The Dolphin Fountain at the Retiro Park in Madrid. I just started this painting last weekend. I’m still working on it. I take photos of the process of painting to have a look at later… The same fountain as above around five hours later. I only paint with natural light. On Friday, Saturday and Sunday. I turn off all devises, disconnect for the weekend and paint all day.
