Here's a really great Naga from Broadsword miniatures.
I thought all the Broadsword figures were sculpted by Jay Adams, but there was a review of this piece in Dragon magazine 84 that credited Bob Maurus as the scultor, so I don't know.
This nasty looking brute is the Madcoil from Ral Partha's Elfquest Personalities boxed set. Sculpted by Julie Guthrie.
And this fantastic Salamander is also from Broadsword. I'm pretty sure this one is a Jay Adams piece.
