Different brush techniques in a painting are individually good but lack visual connection. How can unity be increased?

Correct answer: Maintain some shared directions, colour relationships, or repeated stroke qualities across areas

The governing compositional concept is unity through repetition and relationships. Different techniques can coexist when they share selected qualities such as stroke direction, colour harmony, rhythm, or mark size. Option B creates links without destroying variety. Adding unrelated techniques increases fragmentation, one flat colour removes useful variety, and changing the size alone does not establish a visual relationship among the marks.
