Cathy Williams signature style was first applied in her landscape paintings, which evolved into her painting  distortions of these landscapes when viewed through glass. The abstract series of paintings featuring vibrant colours and clean lines are derived from the distortions found within the glass. Cathy Williams also creates paintings by abstracting from reflections seen in silver.

Cathy Williams takes portrait commissions, painted in oils and pencil drawings.

Recently Cathy has been using fine watercolour pens to produce illustrations and landscapes.
