While art students toil away with charcoal and pastels, few professional artists take these chalky, smudgy media into their personal practice. Jeffrey Richter, however, specializes in pastel and charcoal drawings with a haunting aesthetic made possible by the smoky effect of his chosen media. Opting for chiaroscuro lighting, Richter focuses on isolated figures — femme fatales that are hybrids of human and machine, temptresses of death that emerge from skeletal remains. Take a look at some of his work below.
