I'm not so sure about the Frost Atronachs. Yes they looked awesome in Oblivion. However, they looked too much like multiple ice cubes glued together before. Now they look sorta craggy. I also believe their reasons for adding the bluish aura to them is to represent the fact that they are magically conjured elemental beings and not living.
