I am amazed to see the old Sculpture in the museums. The skill and talent that people had back in the days is truly amazing.
Yes, the unique way that Sculpture deals with three dimensions brings the artwork to life.
They can almost look so real these days with the modern sculptures.
Yes things have come a long way with sculpture.  Stone, metal, wood, creramics etc. can make some beautiful pieces. 
That is a lot of choices for creativity. I like that!
Yes and it also lasts.  Many historical art pieces we have today are stone sculptures.  They can stand the test of time. 
Yeah, if one want it to last for centuries, I think stone or even metal is the way to go. 
Ancient Greek art is a good example.  All those sculptures focused on the human body are a focal point of stone sculpture art.
