[Tumblr's been getting all my artwork recently, so sorry about that.]
My mind\'s been on Portal recently since I'm actually puzzling out a GLaDOS cosplay. Here\'s a design based on the Aperture Science Turret. A while back I also designed a human turret based off the "fat one" who sings, so maybe I can color that and get her up as well.
p.s. drawing guns is hard.
