The previous ancient Dark Elf posting determined that these figures are indeed over 20 years old. While it is very challenging to apply current techniques to something long since out of print, that is very interesting!
It definitely breathes new life into them, and forces you to adapt techniques that are normally used on something that it finely sculpted and cast. The amount of detail and precision on a typical figure of today is astonishing by comparison.
These figures were also never intended for things like NMM, so finding those vital areas of reflected light and color are more difficult.
