The subject and the process of O'Mara's work are intertwined; O'Mara explores the ideas around identity, the fluid and unfixed nature of it.
O'Mara interests lie in the multifaceted nature of ones self and works from images of people that she feels are displaying this. People who are in some way performing, whether it is on stage, a character within themselves, or a role they feel they should be conforming to.
The process of applying paint, then with water and sponges removing and distorting the image is repeated until the painting takes control and the altered image starts to reveal itself as a complete thing – but made up of fragments of itself. This represents the way one’s identity appears in a complete form but is made up of your history, and the different parts of yourself that are in a constant battle to rise to the surface. The fragility and impermanence of watercolour on canvas, a surface that mainly rejects the paint and can easily be moved or erased, mirrors how one small act can permanently change your identity, and how mistakes and chance play such a key part in shaping it.
