Hi Craig, Hopefully there is something here that will help with your project.
I've encluded the original model and seperated & smoothed parts where I think will help.
Do check the sizing suits your needs and do post some pics if and when you take the project on, Cheers Jace
I've included an addition Spiderman Scarlet Mask, but it is very plain. Maybe worth of a look!
Realised afterwards I hadnt cut the holes in it for the eyes ; ) Updated now
