Really nice, what material is it made of? I’m guessing cardboard
Cardboard and Paper Mache! I used a Spider-Man mask sewing pattern for it and overall it turned out pretty well!
Ah yes, my two favourite materials. Maybe for the next one you could try to use a pattern that has more cuts in it to get a better curvature, especially on the top. The other thing you could do is trying to push and curve the cardboard where the seams meet to also get a better curve and if you cover it with paper mache it would look better
for example here I have a helmet I made out of cardboard and you can see that it’s really smooth, not only because i put filler on it, but because i pushed and curved the cardboard to make the curves, almost like you would do with a foam helmet. The back and the top of the helmet are made only of about 5 pieces of cardboard but they still look very good
