Watercolour Masters - Alvaro Castagnet in Moscow - Two Abstract paintings

Alvaro tries to draw two 'bad' paintings but fails each time.
“I choose the palette of the painting in accordance with the monochrome principle. For me, reducing the number of colors is a certain evolution. Recently, I have been using 3-4 colors.
If we talk about the basic rules, the picture consists of 3 types of forms: large, medium and small. The objects do not have clear boundaries, we mix everything to achieve the maximum harmony effect."
