I used a full sheet of Arches 300# watercolor paper measuring 22" x 30"
I enlarged the sketch onto the watercolor paper.
The watercolor underpainting is quickly applied on the wet paper with a large brush in a loose manner, wet in wet washes of dark values and drab colors.
I use soft pastel to locate some of the darkest darks.
adding more detail with the soft pastels, ensuring that the marks help pull the viewer's eye through the painting.
The last sparkles and small details have been added so I sign the piece.
