I was asked to play around with the human version of The Mirror, adding some cybernetic enhancements to her head. Hear are some of those iterations.
I was also asked to try giving her liquid metal eyes that would behave like a ferrofluid.
In the end I was asked to combine the version with the blue jaw and the version with the big grey dome head. This would be the version that made it through to the final film with some added Improvements By Ian Spriggs.
