Vibrant large sunset marsh painting is an original nature painting. It was inspired by a trip to a Florida coastal nature park called Green Cay Nature Center with lush green grass and cypress trees. A long boardwalk goes over wetlands. You can observe alligators and coastal birds in this lovely serene park. Nature photographers were there taking paintings of the wildlife and marshlands. The painting was done with a palette knife in an impressionist style.
