Drawing from his personal life and everyday surroundings gave Morrell greater depth and understanding of his home in New England and these works are what he is best known for. Morrell was a member of the celebrated Rockport artist colony and he is one of a premier group of American artists who continue the tradition of great landscape masters such as Winslow Homer, Edward Redfield, and George Inness. In his harbor paintings, Morrell often uses bright vibrant colors in combination with grassy green boats to allude to the movement and activity of the harbor. His innate connection to the area is revealed through his impressionist brushstroke, thus revealing Morrell’s artistic signature.
Morrell was a member of many artists associations including the American Artists, and the Rockport Art Association. His art can be found in the Butler Institute of American Art, the Columbus Museum of Fine Art, the American Watercolor Society, the Vermont Art Association, the Rockport Art Association, and in private collections throughout the United States.
