Enlisting at age twenty one with the Australian Imperial Forces, Feint embarked for France on 17 September 1916 from Sydney aboard HMAT Borda A30.

Exhibitors included the now-famous Thea Proctor, Elioth Gruner, Margaret Preston, Roland Wakelin, Roy De Maistre and George Washington Lambert.

Between 1927 and 1939, Feint made 18 covers for Ure Smith's magazine The Home, including the famous illustration on the October 1928 issue in collaboration with Hera Roberts.

A newspaper review of the time referred to the imaginative depiction of hibiscus and lantana, the overwhelming opulence of colour, "saved from coarseness by the exquisite delicacy of the textures".

Feint produced his design of Australian birds,[7] accompanied by other prominent artists Frank Hinder, Douglas Annand, and William Dobell.

A contemporary of Feint, the artist Douglas Dundas described his works as 'flower arrangements, meticulously designed, superbly painted, and set in a related environment of time and space'.

By the end of World War II, Feint could justifiably lay claim to a number of titles; gallery director, bookplate designer, printmaker, illustrator, commercial artist, and painter.

The Orient Steam Navigation Company were re-fitting their ocean liner RMS Orion to resume service between Britain and Australia having served as an armed merchantman during the war.

At the time of his death in 1971, the Sydney Morning Herald described Feint as an artist “noted for his still life and flower pieces",[15] commenting that his works are shown in public and private galleries across Australia.

An extensive exhibition of his work, including many privately owned examples, was mounted between March and June 2018 at Carrick Hill, whose previous owner was a generous patron of Australian art, Feint being a particular friend.

Exhibits included a collection of bookplates, and other material, donated by Richard King to the Carrick Hill Trust under the Australian Government's Cultural Gifts Program.
