Caruso's Mask very early concept

That's a very early concept art for Caruso's Mask. At the beginning we wanted to have a respirator and some sort of  Venetian  mask aesthetic into it.

The crystal at the forehead would work as a visual indicator for the player's HP (hitpoints) using a color palette, Blue = full HP,
Green = little damage taken
Yellow = half HP reached
Orange = Low HP
Red = HP are critically low

This is how the mask looks like in 3D

We decided we didn't like the look of this mask and continued brainstorming.
