So, this is my very first mask sculpt as well as my first ever sculpting. I started with a bunch of tinfoil as a base to sculpt around to eliminate the need to buy a lot of clay due to cash. I first drew out the shape according to my references and by the measurements down onto my sculpting surface then put bunches of tinfoil as a base. I ended up only using 10 pounds of air drying clay. Anyone have any suggestions?
