Marsh was born in the West- Midlands, UK in 1979, he is an urban landscape painter best known for his sprawling cityscapes of major destinations around the world.
Marsh has often been described as a "humane" hyperrealist as he adds narrative to the humans in his paintings, conveying genuine human emotion and concern rather than using them to simply clarify scale.
A distinct sharpness from foreground to background is exhibited in Marsh's paintings. His description of light alters according to the seasons and the architectural influences of each city. His use of paint is similarly precise and consistent, with a meticulous technique that involves layering colour and information until reaching a pinnacle of extreme clarity.
