Leigh, when you started this, carving shapes from insulation foam and saying you had no sculpting experience, I thought it was an unusual way to begin and a fairly difficult subject for a first bust. The first set of pictures looked good though, and I was interested to see how it went. As time as gone on you have proved yourself to be a resourceful artist with a critical eye for detail and what looks good. I think what you have achieved here is just astounding to say the least.
As for the base? I think it's excellent and can't wait to see the derilict wire work you are going to apply.
It looks great even now, so when it's finished, it's going to be stunning.
