The model is complete! It was more difficult than I'd expected, but here are a few lessons I'd learned:
When working with epoxy putty, you can control the hardening time and overall firmness by adjusting the ratios of putty. The "skeleton" putty (the thick section attached directly to the pin) should be soft, allowing easier adherence of the "muscle" putty, which should be much firmer, to prevent easy crushing.
Despite the interesting features of the model, there is still a lot that has to be done with paint.
Getting primer between all the tiny strands is going to be a challenge. Plan: many many very light coats.
Once again, excuse all that ugly text around my photos, that stuff comes out of the picasa embed image link.

I appreciate any feedback that will help me improve it before I put the primer on this weekend.
