after the mold of the head has been made, it's time for the wax copies!, i8 made a few and picked up the one with less bubbles and a smoother surface to start sculpting it with some tools o got at a jewelry supplies store.
so it finally looks like this:
the body was sculpted using a mix of 1/3 green stuff and 2/3 epoxy putty (comercial name is Parsec, and it's made in Argentina) to save some money, green stuff is better for small figures, but it's features are quite good for smooth surfaces and sanding, as oposite, Parsec is not that good, but it's cheaper, so the mix enhances parsec a little bit, making it easier to work.
these are the the arms of the figure.
Here is the figure ready to cast, still disassembled, but i checked how good was the fit of it's parts, and doesn't look bad at all :P
