Step-by-step explanation:
One of the most important stylistic features of Van Ruisdael's work is the combination of a composition drawing on nature and an ambitious statement in terms of content. His paintings often depict landscapes with elements such as trees, windmills, and churches, showcasing the beauty of nature and the Dutch people's industry. For example, in his painting Haarlem from the Dunes at Overveen, he portrays the city of Haarlem with a church steeple and a windmill, symbolizing the importance of God and the Dutch people's industry.
