My first mask! Not too bad. The It fits my face fine, but it's a little big on miss head. I learned a lot from this mask that I shall take to my next mask. One, I need to use a thinner elastic. The one I used was too thick and slipped off my ears. also the diamonds are a little too big, so next time I'll make them smaller. But for my prototype it's not bad. I have ideas for many more mask.
