yes I also use sheets of styrene.
The last statue is a biker.
The lower part of the bike is made with pieces of styrene.
The above part is a thin sheet made of superculpey, on an armature in aluminum foil
The materials can be mixed, does not have to be all modeled with the sculpey.
However, these details should be added at the end
I live in a small town, there are not hobby shops ...
The necessary (sculpey, styrene, etc. ...) I buy it through the internet.
Ciao Lucio
