Brian pushed his latest update for the caer concept onto our shared dropbox folder a few days ago. It's really shaping up!
We still need to tweak the posture a bit, and probably thoracic proportions also. For now we've actually decided to work on something else, because we don't want to overwork this model and end up killing it with our zeal. Sometimes it's best to just let things marinate.
In any case, share your thoughts in the comments and stay tuned for the next model.
