1. Positioning
Make it so there is an option to change the positioning of the mask to be angled on the side of the head (this would work similarly to the right/left shoulder placement for pets). This would make it so that the mask doesn't cover the skin's face!
I added a reference drawing (image 1) and Minecraft reference (image 2)
2. Color
Right now in the store we only have a red and white mask. I know people would love different colors
eg) Black and gold; black and red; blue and white; gold and red; pink and white; etc
Color examples are also shown in images
