Which painter's gouache landscape painting is more delicate and subtle? The best effect is like oil painting!

First of all, I must correct one point. Gouache and oil painting have different media, between oil painting and watercolor. Known as opaque watercolor abroad, it is widely used. For example, it can be used as a sketch before creation, or with transparent watercolor, or combined with sketch, or it can be an independent painting. Gouache can be painted with thick pigments, or it can be a watercolor-like Bo Tu with a velvet-like gray tone. Many foreign painters use opaque watercolors (that is, what we call gouache, which is unknown in Russia, France and other countries), and there are also major gouache watercolor competitions in China every year. It is not only a substitute for oil painting in painting education stage, but also a famous gouache painter and artist in China, who is good at figures and portraits. His works include Lotus and so on. If you know English, the older generation of painters, figures, landscapes, etc. They are all good at it, especially landscape painting, which has profound and incisive characteristics and is worth learning. There are many painters, so I won't list them one by one. I graduated from the Oil Painting Department of the National Art Institute of Ukraine.
