sorry about that blank reply - i seem to keep doing that!!
ive no experience from doing any of this myself but from what ive read in the past you could easily make some rough resin moulds * of your basic figure shapes in resin (like a \'dolly\') and then sculpt the details over the top.
that way you have a half made figure already. you could make \'green moulds\' for any facial features and textures etc.
* make a box (eg from lego) ie. walls that would fit your figure with an inch or so of xs at each side. half pour your mould mixture in with your lubricated mini lying on the top, half submerged. once dry, add a layer of lube (eg vaseline) and pour more mix so the box is full. when dry, separate the two halves and you have a mould.
i think the next stage is something like you carve a channel to pour your casting mix into.
if you google search youll come up with some good \'how tos\' after a bit of searching
good luck! :beer:
