All of Erin's pieces share a common underlying theme dealing with space and mass through groupings of people, objects, and buildings. To the person who lives in the urban landscape, finding balance can be an everyday struggle when trying to exist in between the people, the objects, and the surrounding buildings. Erin uses spatial composition as a metaphor for humans’ social relationships with each other, with their acquired and discarded objects, and their environment. The paintings and drawings can be viewed as social portraits of the human-built landscape, and a personal expression of living within a city. Erin works in many kinds of media, many of which are recycled from packaging that would otherwise go to a landfill.
