The pieces show Walker's multi-layered style. He uses abstract and scrawled lines to create his colorful portraits. There is something very "alive" about work by the best artists using spray paint in their work. It always calls to mind "street art." (a term I am personally getting tired of and let's not get into how art not on the street can be street art!). This is fine art using techniques often used by graffiti artists to be sure but it has a style that owes as much to abstract art and photo realism as anything else.
