I've tried to make hallucigenia in its correct configuration with the spines on top and the tentacles on the bottom before, but it didn't work out, so I always defaulted to the older, incorrect configuration with the tentacles on top and the spines on the bottom. This is a new attempt at a more anatomically correct hallucgenia, although I'm still not sure about its front-to-back orientation. I'm also not sure about the shape of the head. The image I used as a source featured an ass-shaped head.
