I had wanted to make this mod for quite a long time, but never thought I could actualy pull it off. but I managed it :D

Sour side-note: I don't really understand shadow/normal maps for DDDA files yet, and there is some shadow mapping on the inside area of the mask.
or in other words, if you turn your char's face to the side you can still see a tiny dark part from where the mask would be. it's not too intrusive, but it can be annoying in the character equiping screen.  (if I ever figure out how maps work for DDDA I will gladly fix it ASAP.)

Enjoy the mod!
