British artist Ben Johnson is in no rush to get his paintings done. In fact, he has spent the equivalent of 17 years on one painting alone!
He is best known for his works that show intricate architectural spaces, and large-scale city skylines from places like Hong Kong, London (you can see this one at the National Gallery in London), Jerusalem, and Liverpool.
These layers of paint create incredible works, but Johnson has said that these creations are not something that he does for fun, but something he feels compelled to do.
The BBC recently interviewed him for an upcoming exhibit. Click the link below to learn more about him and see him at work.
