Are you scared Yoh?

Among the numerous cosplays of Faust I have seen, I must say that yours is one of the best for some reasons.

To be honest the costume itself is not amazing and perfectly representing the character (not completely accurate hairstyle, some clothing elements missing, etc.). Plus I'm not fan of the place you selected for your photo but it doesn't matter too much, though I like the cloudy weather in it.
However what enhance you truely is your general attitude on your photo.

I love your expression and pose which are pretty creepy and powerful since you look quite natural more than just acting. The blood splatter looks real and your chest make-up is somewhat scaring.
I also love how Elisa's skeleton is bending, as it was still in pain.
Even if your costume is not amazing, it gives the feeling of being genuine and kind of true.
In a word, you are a great cosplayer because you really became the character and not just dressed up as him. That's the true essence of cosplay ^^
