It's certainly a challenging figure to make! The blue one on this thread is an excellent purist one, but I feel I'll have to do the odd mod to get mine right.
Until the Patty Tolan piece arrives I've got the dark blueish grey 'swept back with widows peak' (J. Jonah Jameson), slightly off-centre - which actually looks ok against the medium dark flesh I'm using for Saw.
I've just started to build a whole bunch of extremists to go alongside - so many exciting options from the film!
If you want to use reddish brown head for Saw, the Karl Mordo one works very well!
That said the whole figure could be a useful base for Saw, if you substitute the left leg and arms for plain dark green.
