 Apart from his work as a practising artist, he taught from time to time in the Belfast College of Art, where he influenced a generation of students 'especially in the matter of drawing', as he once put it.Although principally a painter, throughout his career he occasionally made sculptures, such as the "Stone Head", "Seraph" of c. 1940 (Ulster Museum)- indeed it was for sculpture that he won the Robert Ross Prize at the Slade School.He was also much interested in philosophical theories of art.
