After reading through this entire thread, I would not presume to critique your work.
As a long-time sculptor, and more recently a CG artist, I’m very impressed, and I am happy to see the response you have gotten from the CG community.
It is well deserved.
Have you considered sending your file to a rapid prototyper, and executing an actual sculpture from your model? It’s such an impressive, detailed work, it would look fantastic as a bronze reproduction… provided you have detailed the entire piece.
Best of luck in your future endeavors
