This looks to be Fuuma (or the 'Kamui' of the Dragons of Earth) from X, by CLAMP.
There's some really nice work put into the shinken. I wonder if it has the Hebrew writing on it as well.
The wings are nice, quite good for not being actually made with feathers. The 'wing' effect was still nicely maintained.
I'm not sure where the source of the outfit is, but it looks well tailored to the cosplayer. The hair... well, the cosplayer has curly hair, and Fuuma's is straight. It is cut into the style well enough. Overall, the cosplayer did a good job.
The dead-on angle of the shot and the orientation leaves something to be desired, however. The camera probably should have been tipped to the side slightly for a more dramatic effect.
thats incredible the wings and everything I dont know who ya suppose to be though.
