Palmer's subjects are wide ranging – from her work with Egyptian mummies, first seen in her 2011 exhibition Unwrapped: The Story of a Child Mummy, to her 2018 portrait of Eclipse, the undefeated Georgian racehorse sired in the bloodline of an estimated 95% of modern racehorses.
Palmer's technical ability, too, is broad: the artist is as at-home working with American black walnut as she is in polished bronze, demonstrated in her 2015 work Lifejacket. Palmer's signature technique is, however, something wholly her own. Utilising modern imaging technology, Palmer reveals the internal topographies of her subjects which she then charts with the aid of an electric drill head. After precise engraving across multiple of panes of glass, careful layers are built up to reveal a three-dimensional portrait suspended in space.
