This was modelled based off of references from posters, and the Hot Toys prototype photos. The helmet was originally going to be used as part of a bust, however I couldn't figure out a good way of modelling the hair so I thought I may as well hollow it out and turn it into a helmet :)

The width of the inside of the helmet (ear to ear) is around 150mm, so the scaling may require a little tweaking to get a good fit.
