Knight of the Thorn

I really want to make a cool/imposing look with the new regrown Caladbolg greatsword. The theme is obviously Caladbolg and the new title you can earn by getting 1 of the new weapons: Knight of the Thorn. After a few hours of mixing and matching and some frustration I came up with this. I'm semi happy with it but I feel like i'm missing something, was wondering if you guys could help me out ^^ All suggestions from styles to dyes are appreciated!
