I had a go this morning using some of the pictures. I'm particularly interested in how figures merge into each other and the background. The colour were raw umber, crimson and cobalt blue.
By the way the images other people have put up of their work are found if you click "comments" under the original post. It's a bit cumbersome I know and will try to streamline it!
Wow - I really like the interaction of the hands with the sculpture! I did some sketches from a book of facial expressions, mainly single colour with mixes I had on the plate.
