Having been raised in Chicago, and spent many years in Spain, it was moving to Scotland ten years ago, that reminded Bill of how much he loved deciduous trees and he reconnected to nature. Trees blooming, blossoming and turning colour with the seasons.
It was whilst grumbling about climate change cynics that the current body of work was inspired. Zima was angry about climate change denial and distracted with these thoughts when he botched a drawing, crumpled the paper and threw it in the bin. After a few moments of reverie, staring at the shadows formed on the crumpled paper, he connected the thoughts of a ‘throw-away’ society with the trees he began to make. Bill writes "I never have a preconceived notion of the colour, the piece always guides me in this regard. I respond to the shapes and patterns of the wrinkles, to draw tree trunks and/or branches with charcoal. Oil paint is used for the overall tree and branch structure. I apply a beeswax/resin ‘glaze’ coating with a palette knife. After the wax phase is complete the whole painting is painted completely black and the oil paint is removed, leaving marks, crevices and traces thus creating a type of visual history”. Zima finishes off his unique paintings by building his own deep-set frames.
