I tried adding a bit of parallax to the head tilt extra impact. It probably needs a bit of fine tuning but I think it sells the illusion well enough.
I realised after I'd finished animating that, because of the amount of movement, the whole thing needed to be a bit slower. Thankfully having covered time-remapping in the class this was an easy fix!
All feedback welcome :)
Another version with a more exaggerated tilt.
