McKinley's work focuses on classic and contemporary architecture. He doesn't usually show the humans who inhabit these structures in his work. He more alludes to their existence in the details--the furniture, art and other accoutrements of the fine homes he paints.
The artist was born in Michigan and studied at Brighton Polytechnic, Ravenshourne College of Art (London) and at Falmouth School of Arts. In the USA he studied at Goddard College, Vermont.
