Really amazing job with all three, I really endore the different special backgrounds on each three, I suppose that it's some sort of characteristic for each one of them. Espically with the Zalkar whom seems to have the Tamriel map behind him, lookes insanely neet!
Not to mention the sexy lady in the middle, looks really awesome, I espically like her dress with the different colours and patterns, it works really really amazingly well all together!
However, I still adore the way you painted Night, you really nailed that mask to perfection. The most important element of him, and you got it amazingly right! =P
