Dennis trained at the Birmingham College of Art and the UCE. He has exhibited at various locations including the Ikon Gallery, the Royal Academy Summer Exhibition and Taksu Gallery, Malaysia. Prizes won include the Cadbury Drawing Scholarship and the Pastel Society 'Inscribe' prize.
Dennis has conducted personal research into Islamic Architecture and Pattern and Japanese Wood Block Printing. As a starting point for his work, Dennis uses famous portraits. Whilst altering the meaning of the image, he endeavors to pay homage to the artist's skills. Large parts of Dennis's painting stay close to the original, but the figures are transported into an exotic, colourful world alongside another figure from a different time. Animals and objects act as symbols to signify ideas such as human strength and frailty.
Artist Statement: "For this recent collection of my paintings, I have chosen to return to my life-long fascination with plants and flowers. The endless range of vibrant colours, strong abstract patterns and textures that even the most common plants can offer, has long seduced me".
