Alex's concentration section focuses on integrating Zen tangle patterns and lines to create imaginary aquatic creatures and environments. They began with vibrant uses of color and line in the first five pieces and then incorporated black and white to create a more somber mood. Their skills in different media, like precisely drawn patterns, are displayed. The purpose is to bring joy to viewers by combining originality, technical skill, and changing moods through color schemes. The 12 concentration pieces demonstrate Alex's exploration of this central idea.
