Well I just can say, this is an awesome picture. I can see every detail of his clothes. His face fits perfectly and anything about him seems to bee very detailed (is that a word?) I realy like his background story, which is prety good writen. (I do like that kind of storys) The key -sword fits perfectly to him just like the background. With this awesome colors and symboles, it gives the picture a dark and prety cool effect.
I think you should defenitly make more about him.
