Other noteworthy landmarks in his exhibiting career were a second prize in the 2nd International Drawing Biennale in 1975; a second prize in the Spirit of London show on the South Bank in 1983, with a first prize in 1985; the Daler-Rowney Prize at RA Summer Exhibition in 1988; and solo exhibitions at Cadogan Contemporary from 1991.
