Character Design

My character is the partner of the Lord of Death, Nagash. She is a part of the Death Alliance and is equal to Nagash (virtually the queen or goddess of death). I tried to keep to the same atheistic as the rest of the Death Alliance by using skeleton influences, similar armor and Egyptian influence that I could see in the Death Alliance. 

 Here my character looks a bit too alien and not human enough. I think having horns doesn't work with this character.

 I referred back to Nagash's design and designed the characters armor very similar to his. I am struggling a bit with the costuming for this character. I will have to research some different cultures to see what will bring her to life.

 I noticed that Nagash had bones coming out of his back so I thought I would apply this to my character. I'm thinking if they have too much in common they'll be mistaken for siblings or family members instead of partners. 
I also started experimenting with the staff design here. 

 I carried on with the idea of a bone structure coming out of her back but this design over all looks like a religious figure. I want her to look like a goddess or empress but this is too close to the Virgin Mary to me. I experimented with fabric design as this isn't common in the Death Alliance character but could be a nice point of difference. 

 I tried to mix all of these ideas together (the bone structure on the back, the fabric and the Egyptian influence) and came up with this mess. This is just a muddled design that isn't successful at all. Too many ideas that aren't executed well.

 Again I tried to throw all my ideas into one design and it didn't work too well. It's not as bad as the last one but still not good.  The crown is too masculine and pointy, the bone structure on the back is too close and random and the fabric trail at the end doesn't look good. 

Because my character is the Lord of death, I thought having her very skinny and skeletal would emphasize this idea more. Looking like she is on the verge of death brings her closer to being a god of death. I like her head thing but I think its a bit too oriental looking. I think this has too many ideas but its a lot better than other designs so far.

I'll get some feedback from my tutors and see what they think of my progress so far.
