Things have been very busy but unfortunately no sculpture work at the moment.
When I finish a sand sculpture I usually spray a very dilute coat of PVA on the surface. This stops the detail from drying out and blowing away. Although they are temporary they can last for a few years.
I am still looking into NFT. Not really sure what the long term value of them will be but it is crazy the amount of money being pumped into it.
Thanks @nineclaw and hope you are getting on well
