As you can see, the plan is to make the visor of the Extreme Depth Suit transparant, so you can see Lara's head inside.
Although there are special printable transparancies, those are quite expensive, and since there won't be any special textures on the visor, I think it will be better to just use a normal transparant sheet.
I'm anxious to try it out, because I think it will look pretty nice! But for those that can't be bothered with the transparant parts (it will make assembling the torso a bit more difficult...!) I'll also include an opaque visor. ;o)
