This is my Storm Atronach from skyrim

Description from TESWIKI-

Storm Atronachs are a form of Daedra that can be summoned using Conjure Storm Atronach. They are commonly summoned by Dragon Priests, giving them a powerful minion. There are two types, the other being a Storm Thrall, which is a master level Conjuration spell.

They travel by floating, similar to a Flame Atronach. They can travel over water, and are slightly faster than Frost Atronachs. Their physical appearance seems to be an assembly of rocks conjoined by bars of electricity. Their face seems to be carved out of the stone itself.
