I like it, especially the use of the Acolyte Mantle. I'm using that for my Necbro which I'll post later this weekend. A couple more screenshots would be nice though and I likely would have used a few more shades of red and black in order to help establish a bit of contrast in some elements. Otherwise, good job.
I love the combination of red and black together so I might be a bit biased. (I use it with at least three of my own characters) Oddly enough whatever you did when creating the face with that hairstyle has an uncanny resemblance to someone I know. All in all, a great job. I just wish there would have been more screenshots and a little more history as to why she is considered a fallen angel.
