Click here to read Raven's review of Jonathan Delafield Cook's current exhibition at Olsen Irwin. "Cook?s skill and precision are astounding, particularly considering that his drawings are executed in charcoal ? a notoriously unforgiving medium. A combination of direct observation, often from museum specimens, and photographic references inform Cook?s work. His notations of flora and fauna border on scientific, with form and texture impeccably reproduced against clean white grounds." - Raven [caption id="attachment_1672" align="aligncenter" width="550"] Jonathan Delafield Cook, Mackerel VIII, 2013, Charcoal on paper, 15 x 43cm, $3800[/caption]
