John paints the surrounding Argyll mainland and island landscape, but is equally at home painting in France and Holland.
His style is partly Expressionist, where he uses some distortion to express the feeling of wind on buildings, but also with a touch of Scottish Colourist in his use of light and colour.
He nearly always uses the images of crofts in his landscapes, although not exclusively, and has a "Romantic" view of them, drawing on his island roots.
In 1985 John began signings with "JOLOMO". John says "I try to paint beautiful paintings as I also hold closely to Monet's statement that 'beauty has a healing power.'
