After thirteen years in Sweden, he returned to England in 1965. By 1970 he had moved away completely from technical illustration, and in 1980 he became self employed. In 1990 he began to paint aviation subjects, which by pure chance contributed to the rekindling of his Swedish connection.

In 1995 Roger was honoured with a one-man exhibition at the Swedish Airforce Museum. He has exhibited regularly in England, Scotland and Sweden, and has also shown his work in Norway and the United States. Today, he is a full Member of the Guild of Aviation Artists and a Fellow of the Society of Architectural Illustrators.

He has received numerous artistic awards and trophies during his life, including the Society of British Aerospace Companies Trophy, The Wilkinson Sword Trophy, Aviation Painting of the Year Award, The E.J. Riding Memorial Award, Westland Helicopter Trophy, Winsor & Newton Award, Qantas Trophy, and the Roy Nockolds Trophy.
