All the work in the exhibition is new.
He says Lin's work is more contemporary, but David would like to try more abstract work.
"This one is a piece of music," he says, describing the brush strokes as movements of a conductor's baton. "It's like every note of a sonata." Music plays a big part in David's life. He has a Steinway grand piano and counts concert pianist Michael Houstoun as a friend.
He has deep regard for the art of his friend, Greg Lin.
"Mr Lin's work is exciting, with colour and arrangement of depth."
Each artist paints differently, with David producing a completed work in hours, while Greg will take days or even weeks and multiple layers to create a painting. Each man paints with emotion and the pictures are formed mentally, rarely from photographs, although one work by Greg is based on an old monochrome photograph of Maori canoeing the river.
The style is definitely not that of a New Zealand-born artist, with shapes and perspectives which can only be described as Oriental.
I liked David's use of broken lines to create form and shape.
"I like to feel the emotion," he says. "I don't like to make it very correct. It's like I compose my paintings, like a small orchestra, or a trio or quintet ... just feel it."
Once explained like that, the viewer can see each instrument as it adds to the overall work.
For pianist Tamas Vesmas, David once painted 24 works to accompany a presentation of Debussy's Preludes, performed in Paris. David's paintings were projected above the stage as Vesmas played.
Oriental Perspectives of the Whanganui River is on at Fine Arts Whanganui Gallery until November 5.
