I’m just now finding this jewel of a painting and I love your selection of complementary green and red tones. It shimmers with light and the texture is awesome. Love, love, love it and am sure at that size it is impressive upon a wall.
Thank you all for the comments!
Foam covered the entire canvas. Foam is the background on which I apply the paint. Sometimes, with foam, I make some parts of the painting volumetric up to several centimeters. It depends on the context of the image and on the conceived idea.
If you bring the image closer, you can see a strong relief of the canvas. This is foam.
