I noticed that when using the NoMaaM Breathing Idles Mod your armour actually bends under the pressure of your dovahkiin breath. And I understand with us being THE dragonborn and all, but it really breaks the immersion when you look at your character and your ebony armour deforms like a water bubble.
I'd suggest removing it from the S.T.E.P Guide.
EDIT: Or maybe ask the mod author if it is possible to make it in a way that does not break the protective sturdiness of some armours.
