Transparent Underpainting

OK, Here it is!  The photo of the transparent underpainting.  Just fooling around with transparent paints and two panels.  Pretty, isn't it?   I used Alizarin Crimson, Indian Yellow, Sap Green, and French Ultramarine Blue.   Except for the sky and a few spots of reflected sky in the stream, all other areas are transparent paint.  The sky is French Ultramarine Blue and Titanium White.  Any time you add white to a transparent paint, it is no longer transparent.
