The works of Truc are introspective and atmospheric. With a minimalist approach, he captures the spiritual essence of nature.

The purity of composition and meditative color scheme in Truc's paintings recall the Zen-Buddhist philosophy that empty space is as important as an object. In keeping with this philosophy, the open space and monochromatic nature of the paintings leave the viewer in meditation. Truc's art conveys the romantic simplicity and timelessness of Vietnam’s countryside landscapes. Part of its charm lies in how details of each scene gradually come into focus - streets, houses, lakes, and trees typical of Vietnam.

Colour, many layers of the same shade, is his tool of description. From within the monochromatic canvases of red, blue and green, subtle silhouettes emerge against the openness and space of the landscape. Like a dream lingering in the eye of the waking mind, his scenes recall a past memory.
