Progressing, bit by bit...
This is drawn, I think, with a 2B in a .9mm technical pencil. It's on it's way to becoming, I hope, a watercolour. Quite large - 14" x 20" or 36cm x 51cm, Aquarelle Arches, 100% cotton, 300g/m or 140lb. I've done the shadows and the beautiful wrinkles in the skin lightly in the drawing - knowing that soft graphite will bleed into the water and paint.
Not sure whether to make it a very detailed, more realistic watercolour, or allow the paint to run freely for a more suggestive rendering.
