Not really. It doesn't dry, it holds its shape well, it's temperature sensitive to your fingers so you can easily get it soft or hard. And it's a polymer so it's very very smooth. The hardest part for me is getting the wire framework right because if you screw up the proportions at that stage and don't realize it till later, it's very hard to fix. And the weight of the clay bears down on the wire and changes the pose. But I would much rather work in super sculpey than stone or even clay.
