This is a quadriptych of a sun rising over gently sloping hills, which I painted last year in June, using Lemon yellow, Payne's Grey and Indigo. Each panel is 30x40cm.
It is currently for sale in my artfinder shop at: www.artfinder.com/manage/elainesaulnierdettmann/product/frillensee-bavaria-7de9/
Here are some more closeups and images of the process.
