Her subjects are drawn from her immediate environment, imagination and memory. The fusion of her two previously distinct streams of Naive and Abstract works is an important milestone in her art practice development. Campbell's technical skill, draughtsmanship and ability to create harmony from discord is a result of constant and consistent work in the studio. Campbell is fearless in her experimentation and is a risk taker in the studio. This has resulted in the steady and continuing growth of her art practice and the ability to work on paintings until they are resolved. Some paintings take many years to resolve by re-working and re-painting until she is happy with the results. She works on several paintings at any time, both on canvas and on paper, in rich bold oils.
