In 1989, Scott participated in the first of several shows in Japan. His work consistently sold throughout the country. Shows were held in all the major cities in Japan. Two of the shows produced color catalogs that featured works by Mr. Jennings. The 1988 festival celebrating the 20th anniversary of the Wild and Scenic Rivers Act commissioned Jennings to produce a poster for the event. Scott was invited to spend a month as a guest of Rocky Mountain National Park in 1986. He was the first painter given the honor of "Artist in Residence" at the park. The 1985 Wilderness Art Exhibit chose Jennings' "The Elk Range" as the show poster for the event. Jennings won three awards at the 1984 New Mexico Professional Art Exhibit. His painting "The Rio Grande Gorge" is now part of the collection at the state capital in Santa Fe.
