The definition of a sculptor is an artist who takes a material and molds or carves it to make a finished product. An artist who takes a lump of marble and carves it into a statute is an example of a sculptor.

I can’t draw very good my art is only good when i’m high
I'm an amateur at digital art, so my suggestion may not be as useful to you. I suggest using the RCA Cambio, It's 32GB and comes with Paint 3D. It's also a laptop/tablet hybrid, so it's good for other things too. I got it at the affordable price of $120 at Staples
Thanks!
