Did a little more work on this piece today - shaping the edges to have a definite contoured asymmetric line. Also spent some time smoothing parts of the surface with wet and dry to see how the colour looks - it has a warm semi-translucent appearance which is very satisfying. The big lump of stone on the right is another piece of Purbeck that I'm going to start - I'm thinking of another curled up figure in this one, we'll see how it goes........
