Joanna paints in many mediums, but her most well known work is in oils. Her background in interior design and specialist decorative affects influence both her compositional style and her love of working with pure gold and silver leaf, as well as other metal finishes, including platinum and aluminium. It is this fusion of luxurious elements and emblems of natural beauty, such as flora and fauna, which hallmark her work. Birds in flight strike a particular chord with Joanna and is the most enduring theme running through her work.
Gold rings and spirographs translate the religious halo into a modern symbol of wonder. The influence of Japanese art is evident in her use of blossom and in pared back composition studies.
Joanna regularly exhibits across the UK and internationally has shown in New York, Stockholm and Singapore and in private collections in Germany and India. A large component of her work is in the undertaking of private commission both residential and commercial.
