What a treasure house of information your site is. I'm bookmarking it and I have subscribed to your youtube station so I will catch all the videos you make. I'm so thrilled. I know I will learn a lot from you.
I just watched the "Wildlife Art Painting a Tiger Tonal Underpainting - Jason Morgan " and how you do it is a totally new technique to me. I mean covering the whole canvas with the acrylic underpaint and then wiping off the lighter areas. I'm definitely going to try this.
The only question I have is something you said in the video. You said that acrylic generally dries lighter. Did I hear that right? I thought acrylic generally dries darker not lighter. Anyway, I definitely am an instant fan of yours. How wonderful that you are sharing your knowledge.
I encourage all painters to give it a 'look see'.
