The original design is from Jim Phillips as I explained in my first attempt at recreating his "Screaming hand" as a 3D sculpture.

But what I ended with back in 2013 is very far from being accurate !
Here it is just to remind you if you haven't seen it yet :

So I completely made it again and started with a hand scan I downloaded, without being able to tell you where I got it from because it was quiet a long time ago.
The scan is very close to the original pose so it was just a matter of sculpting the details to get closer to the original 2D drawing.
And all this sculpting was done in SculptGL.

Once happy with the overall look, I just added ready-made teeth and a tongue downloaded from here and adapted them further before to perform fusion boolean operations.
Of course the result isn't perfect, and will never be, because making a 3D out of a 2D drawing is allways a matter of interpretation.
But I think this second version his way more true to the original.

At human scale the printing time for this sculpture is 18h57mn.
But I mistaken in scaling it so it's bigger than expected with a 23h32mn print time :

The supports were quiet hard to remove but with patience and the right tools I was able to get rid of them :
