Curved fold mask

Lately I haven't done much folding since I came to Hong Kong/Shenzhen China, primairly because I have no acces to the correct paper. Also still haven't both any correct paper to do good folding, howeve I just tore out a piece of paper from my sketchblock and fold it double to increase the strenght to be able to do a curved fold. Here is a first time go at trying to fold a mask with curved folds. Some of you might have recognize the shape of this folded design, it is a Masked Rider mask or in Asia known as Kamen Rider. However the shape and size might be bit asymmetric, because I drew and made it with out any rulers or computer, just with a pen and my hands. However pretty interesting if I need to have a makeshift mask for a party next time I could fold one instead.
