I like the direction this build is taking.  I'd like to see more detailed role-playing.  From what you've written, this guy doesn't seem like the type of person who would interact well with people, making small talk and saying hi to the citizens in towns.  Does he enter cities?  If he does, does he have extremely limited interaction or perhaps cover his face in some way so that no one knows who he is?  

Another thing - "You are an evil character so doing and helping as many evil characters as possible is a good idea for this build"

I get that the character is evil, but does that mean he has to assist in every evil deed?  Considering he seems pretty focused on getting the bones he requires, it would make more sense if he engaged in evil deeds that only act as means to his own ends.  Not many of the Daedric quests seem like they would be very beneficial to him.  So maybe think of some specific quests or specific evil deeds he could justifiably do, rather than having him unquestioningly carry out all evil deeds that are presented to him.  

I do really like the picture selection.  MTG art can capture something like this so perfectly.  I'll keep watching this build, I want to give my +1 eventually, because it does have potential.
