First of all I am blown away by this piece and the details you have put into it, and as a huge fan of this I have to ask if you have ever considered how awesome a costume this would be ? I know I would try and see if I could create something like it if given permission of course.
A chilling design, on that I rarely find. I doubt you would find something so fine for this character looks like it's about to change in an instant of time. Well done my friend this is truly a fiend of something ready to change into anything.
