Greg, your sculpt is so solid, and your attention to detail incredible. The fact that it is also printable speaks a lot for how you approached the building aspect that needed to be respected.
The combination of the easily readable strong pose plus a single image that tells a larger interesting story caught in the moment depending on the angle that you view it --
is not easy to do, but you always seem to bring the whole package together! I really like the Joker's smile with the surprise he has behind his back.
How can such a wonderful figure can be canceled when it has aldready been fully prototyped... Was it a commercial/licenced job or do you own the rights over your sculpt? Can we ever dream of running a little non-official/personnal batch? (I fear I already know the answer, but it's worth asking!)
Anyway: wonderfull job, too bad it will remain stuck in the virtual world
In my opinion, the joker looks too plastic, but it is probably your intended effect. Generally I am very impressed, it is a really professional job - better than in animated films.
