Beethoven - A Force of Nature (Update)

Here is an iPad shot of the larger pastel in progress. I decided to add some elements to the background to tie in with his pastoral symphony as that is one of my my favourites of his. I enlarged a photocopy of the reference image of Beethoven and close cropped it and placed it in on top of the pastel to get an idea of how it will look. The cut out portion is the head and the "kerchief" portion of his coat, not sure what you call that part.
