Well despite boxing everything up in preparation for a move to a new house, I have managed to sculpt up a bipedal alien of a decidedly chitinous nature:
He's a bit of an experiment to see if its possible to sculpt in 15mm scale using sculpey. The results are quite promising as the beast stands approximately 25mm tall and almost as wide and is sculpted from a combination of super sculpey and kneadite greenstuff.
I have a few more of the little fellows on the go at present but once they are all complete, I will be offering them up for sale to whoever would like to purchase the sculpts for casting.
All the best!
