Kestin Cornwall is a creative based in Toronto. He grew up in the Windsor, Ontario area. His father is Grenadian, and his mother is American. During his youth, he spent time with his family in Detroit, Michigan. Cornwall began training at Sheridan College Institute of Technology and Advanced Learning in Oakville, Ontario. While he was completing the Art Fundamentals and Illustration programs, his interest in the arts grew significantly. Cornwall combined classical drawing and painting with modern digital reproduction and screen-printing. He won the CAPIC Best In Show in 2006 and London England's Young Guns Emerging Art awards in 2019.

For the past 14 years, Cornwall has focused on creating progressive and relevant art. He uses various techniques involving hand drawings, digitally removing the human hand, and reintroducing the human element into his work. Cornwall's art explores culture and humanity's relationship with beauty, sex, nature, and a history of cultivation. Additionally, Cornwall's work aims to ask questions regarding equality, immigration, and what it means to be Black in North America. Cornwall's images explore how culture and entertainment, including film and other media, shape the public's perception of Black people and people of colour in North American society. Cornwall also critically examines political, social, and economic landscapes through compositions referencing media, popular culture, music, and art history. He enjoys challenging what's considered "common" and feels it is the duty of an artist to add beauty to the world while invoking the unending social responsibility to capture thought, based on a lesson from Chinese contemporary artist Ai Weiwei.

Cornwall's influences include contemporary graphic realism, street art, and old comics, with a complementing factor of mystery that often mirrors timeless depictions of pop culture. Each of his pieces represents an analysis of our obsession with ethnicity, beauty, age, and change.
