H2 eye cuts

I wanted to turn the TOTS Kirk mask into the H2 mask. I was wondering if I should stuff the mask first then draw out the eye cuts or have the mask on a stand un stuffed then draw them on? I haven’t received the mask yet I just wanted to make a plan. Thanks!

If you’re working with a sculpt that isn’t designed with a particular stretch, the best way to cut them is to model them after photos of the mask unworn.

How TylernolSP said, model the eyecuts after the unworn pictures of the Hero. Here’s the clearest picture I have of the unworn Hero, hope it helps.

Thank you both very much!
