Today it is an acrylic. Am taking a summer class with Cathy Mabius and using my acrylics. Still learning to use them and get used to the values as they dry. This 15"x7" study is for a future watercolour I have planned for a friend. Was painted completely with a palette knife and I love it. It is going on my living room wall very soon! Title - "Moody Bleus"
