Finally got around to finishing the project-after-the-tutorial, plus some extra work. Feedback welcome, as I prepare to put this on my own site in a bit.
Learned some hard lessons about how far I should take things like micro-bevels in Plasticity, as no matter what I did the exported mesh inevitably had some issues especially when UVing. But there is only a little rebuilt geo here; most of it is plasticity exported polygon-soup.
