Esme Weatherwax II
These pictures of the "greens" sculpted by Kul Asyrk were posted to coolminiornot. Not sure about Esme Weatherwax II but the others are all spot on.
I recently finished painting a commission of eight Discworld figures along with the cobblestone bases that you can also purchase at MicroArt Studios. Pictures will be posted soon. I should point out that whilst most of the Discworld figures require 30mm bases The Librarian and Luggage, whilst being 30mm in scale, actually have 40mm bases.
