Sam Falconer's illustrations combining vibrant characters and intricate environments have been commissioned by clients ranging from leading national newspapers to renowned science magazines and universities. Initially working purely by hand, Sam discovered a passion for digital collage in 2010 which later developed into his own unique brand of rich and detailed imagery. This method allows him to develop complex pieces with diverse character sets each distinct from one another. Sam was featured in IdN magazine's New Faces of Inspiration issue as one of ten leading illustrators in the editorial field.
