Diane Griffiths is a self-taught artist who grew up in the Midlands, spent several years in London and moved to Newquay in 2017. 

In December 2024 her painting, Driving Home, depicting a starlit Texaco petrol station on Trevemper Road near Newquay, won the People's Choice Award, as a part of the British Art Prize.

In July 2025 Diane's painting Insert Coin to Begin, which depicts a Newquay amusement arcade by night, reached the top 50 of the 'SAA Artist of the Year' award. This made her eligible for the People's Choice Award, which she won in November that year. The painting was praised by the judges for its 'playful chaos'.
