Previous feedback suggested I try drawing on black paper with chalk. I focused on the ring and shell and tried to fill the A2 sheet. I also used a viewfinder to look at the composition which I found useful.
I used a white pencil to lay down the general shapes and then used chalk to make highlights. I also used a putty rubber and oiled charcoal to put some dark areas back.
I was pleased to find that continuing to work into the image improved, rather than ruined it. I like the simplicity of the final image.I was also pleased that I managed to work on a larger scale .
