The work of Juan Francisco Casas has blown me away – all of these pieces drawn with shit loads of Bic biros. They are also MASSIVE, a couple of meters tall… His method is ‘simple’, first taking a photograph of his subject then replicates them with pens. I particularly enjoy the fact his works are getting less and less SFW

I am totally amazed, especially by his render of water!
