Would something like that be of interest here?
I've been sculpting with polymer clay for a long time.
At the same time, I'll find out how loyal the tournament community for Heroes is to creative works =P.
Here's some fan art.

Solmyr

Behemoth

It takes 1-2 days to sculpt something like this. The material is polymer clay. Different brands – Sculpey, Fimo, Premo, and others.
What do you think?
