You're welcome. No worries on delayed responses, we all have real life to deal with too and things are very far from easy now.
Wow, with regard to what you say about ice. I've never done it, unless you count the weird snow and ice "sculptures" when I was growing up. I've also never had the chance to talk to someone who carves ice and snow, plus those incredible sand sculptures, so it's a great learning opportunity. Ice makes me think of glass, due to the translucent and transparent qualities. I like the idea of "temporary" very much as well, and the challenge you have in working with ice like this.
