(Don't worry, I knocked Aydel unconscious so he can't make any awful, AWFUL cheap joke )
Aw, they look great, both of them! Great concept for the two entities of Order and Chaos! (Because yeah, they both created everything, even though Anu is much more of a creator than Padomay )
If you're looking for duos in the Elder Scrolls, there are tons of them. Especially Lorkhan and Anuiel/Akatosh (I say Anuiel because Akatosh also have a part of Lorkhan/Shor in him.) Or even Tiber Septim / Zurin Arctus! THE UNDERKIIIIIIIING!
Actually according to the wiki, Padomay/Sithis was actually more of the creator at first, being that he first created the Daedra I believe, the Aedra were an accident because of Anu but yeah I see what you mean. Sithis is of course Chaos and Death.
It is awesome - the contrast between the two resides in the colour (dark for death, white for life), what the smoke-like aspect of their respective outfit shows also they are united. Not sure if I am clear...
