Barry McCann is worth watching any time. I have posted two of his sessions before on the Forum.
Watch for the transparent primer, used to seal the drawing and provide a tooth for the acrylic paint.
Transparent gesso does the same thing for oil painting.
Beautiful technique, a nice balance of method, procedure and looseness. Very helpful and informative commentary as he paints.https://www.colourinyourlife.com.au/tv-show-ep/barry-mccann-3/
