I drew this while writing my most recent fanfic which is roughly based on the world of Black Lagoon. Foolishly I thought, hey, I can use Mai Hime characters and stick them into this dark, dirty, and painful life of villains.
It's just a preliminary sketch; there will be a much better photoshopped picture later. I used the Doropanda Tours Dojinshi as the reference material for her face. Obviously used Black Lagoon material as reference to the outfit and guns (not like the shirt was all that complicated though).
My main hope is to draw a picture of Yukino as the Sawyer equivalent or Mashiro and Nagi as the creepy vampire twins.
