Art and illustration 
As seen in his television appearances, Dean produces watercolour cityscapes and architectural renderings or illustrations. These are done in a wobbly line pen and ink technique with evocative colour washes, and are vaguely close to the style, technique, and subject matter of the architectural artist Stephen Wiltshire MBE and influenced by the English tradition typified by Samuel Palmer.
