Philippe Pastor's "Kenneth Bigley" employs a mixed media approach combining pigment, paper collage, and layered materials on canvas to create a portrait that reflects on the British engineer's tragic kidnapping and death in Iraq in 2004. The work utilizes collage and mixed media techniques to build a complex visual narrative, likely engaging with themes of loss, international conflict, and human vulnerability. Pastor's layering of diverse materials creates textural depth and formal complexity that mirrors the emotional weight of his subject matter.
