column tracing drawing

This is the design for the columns in the dinner scene of my 'Seven Ravens' children's book. I've been working out the details of different elements in the room on tracing paper, so I've been scanning and/or photocopying them so I still have a good copy of the original design. I've got the empty wall space to work out and then I should have the illustration finished. After that, it's on to watercolors.
