In Ducks (Lot 1085), hundreds of ducks crowd the foreground, gathering between the water and the farmers tightly. Ran In-ting carefully depicts every duck in detail, using a swift curving line of the neck and head in shades of burgundy and colbalt, reflecting their iridescent feathers. In order to convey the swarms of ducks in the far distance, the colors gentle fade into a further diluted colour, exemplary of the artist's careful control of his brush and the balance between colour and water. Over the sky and water, translucent blues and purples wash over one another to convey movement; the fast shifting clouds perhaps signify the coming of a storm. Similarly in Village by the River (Lot 1086), Ran In-Ting re-creates a serene riverside village, encapsulating all the possible activities by the villagers into one compact scene. In the foreground women can be found washing hastily while the men hale water and goods back and forth while one lone oxen is hurried along the streets. The beautiful red tiles of the houses are even captured, offsetting the deep green bamboo trees in its surroundings. With quick dashes of his brush Ran In-Ting renders the numerous leaves of the bamboo to contrast the long swift strokes of the water, capturing the realistic characteristics of each object with utmost dexterity.

Ran In-Ting's watercolours are simplistic and tranquil in their depiction of the daily lives of villagers and fishermen in the rural regions of Taiwan. In taking careful consideration of the work's composition, Ran In-Ting brings the viewer into the very scene, creating an intimate setting for the viewer, himself and the depicted landscape. Demonstrating his deep understanding of Chinese brushwork technique and the use of bold colors, his paintings are vivid and a unique interpretation of Chinese brush painting.
