Really? Seems about right considering the positioning. Also, they sometimes get around problems like this by hanging skulls and trinkets off the membrane/feathers/whatnot. I'm pleased with the simplicity of the model.
The bangles and flames are cool. The staff looks great. I particularly like the enlarged, predatory toe and the detailing on the face (although the beak-teeth combo make my biologist side twitchy).
Overall, great model. Now all they have to do is make the great unclean one about twice the size.
