 After marrying Hansen's sister, the painter Anna Syberg, his works became brighter as evidenced by his landscapes and the 18 large drawings he completed in 1895 to 1898 to illustrate Hans Christian Andersen's "The Story of a Mother", now considered to be among Denmark's finest drawings.Thereafter, his oils include "Dødens komme" (1906) and "Døden ved vuggen" (1907) and landscapes depicting scenes from Funen, first around Dyreborg and Svanninge such as "Forår" (1893) and "Aftenleg i Svanninge Bakker" (1900) and later the area west of Kerteminde where his garden and children were the main subjects.Quite early in his career, Syberg began to paint watercolours but it was during his three-year stay in Pisa with his family that he completed a whole series of watercolours adopting a style that was new to Danish art.
