The prototype of my techpriest costume, wore it to dragon con 2009 and the reception was pretty good, just need to make the mask easier to see through, one woman was even angry at me when she found out I had not entered it into the costume contest.
it is just what I would think of when I think of a techpriest. a very emotionless look to him/it (how ever you would describe the followers of the Machine Cult... I would doubt that it would make a difference between gender)
