Can't say for sure, but from the pic it looks bigger than average 1/8-1/7 bishoujo scale.
Second, I'd bet it is mixed media.
Third, no hint of anime style on this one, which would be strange for Shunya.
But some way I like this interpretation of Red Riding Hood.
P.S. This one is in fact made by Elite Creature Collectibles, and yes it is mixed media.
Wish it was sculpted though...
