Thank you for taking time and commenting Anne, Patrick, Donna, Arty and Terri.
Terri, In fact I lied with the posture of the snowboarder. In the moment I took the photo he jumped into the scene from the left and I thought, wow this must look exceptional in the photo and when I checked the image later, I found I got him in a second his movement looked really awkward and he had a white parka difficult to separate from the snow, ...
At the end I studied license free photos with snowboarders to find a fitting posture and changed the colors of his parka. So I used artistic license to get it work.
