Onejessa's work is centred around the uniquely human attribute of self consciousness and the impacts this has on the way we relate to our external environment. She explores concepts of mortality, religion and societal hierarchy, and how these constructs impact our changing relationship with the natural world.
Her opulent assemblages are both a celebration of our indissoluble connection to land, and an exploration of our immense destructive and creative power as stewards of this planet. By combining images of natural ecosystems with images and colour schemes that arouse feelings of wealth, nostalgia and decadence, she raises questions surrounding the constructs of modern society and challenge our consequent disconnection from these natural ecosystems.
