...The preponderance of black in MacKinnon’s compositions endows drama, but it also serves to unify the various techniques and media. The artist employs oil, acrylic and auto-body enamel in the same pictures and contrasts precise rendering with looser brushwork that verges on abstraction. The distinction reflects the divide between man-made and natural: Lush vegetation and night skies inspire a freer hand. It also reflects the moods of an artist who writes, “Each day I come into the studio feeling different.” Rather than harmonize these emotions, he juxtaposes them extravagantly, under the cover of darkness.
