In this picture, the artist pays great attention to emotion. The name of the work “Echo” also indicates its content. Everyone knows that an echo cannot be seen or touched. It can only be heard or felt. In fact, an echo is formed when some sound hits an obstacle and returns back. It could be music, a scream, or even a simple whistling sound. But it evokes a special feeling in the listener. The artist tried to express such feelings in this work. It is irregular, without a definite pattern, but bright and colorful. At first glance, the picture seems to be a mixture of different colors, but if you look closely, it will take the viewer into the depths of the work. Each viewer feels a different emotion in it, each emotion manifests itself in a new way and in its own way.
