No, this was all done free hand. I look on sand sculpture like the sketch itself. The fact it allows you to work so fast allows that. From looking at the materials you use i can understand that more planning would go into them. Sand sculpture can last several months to a year outside. Indoors I have known them last for years. The sand is very compact and as it dries out it turns to a soft sand stone texture. Thanks for your question.
