thanks guys.
the neck measures 15inch in diameter, is the same as my collar size.
Phil, the hair has been the biggest pain for me, i hate sculpted hair but its what the client wanted. i made it neater as they are going to be offering copies so i was thinking about the mould and undecuts ect. i am going to sculpt some finer wispy bits of hair onto a casting in sculpy which then can be moulded separatly and glued on.
