This is a lovely photo and the costume is done wonderfully. Not a big Final Fantasy fan myself, but I do love Amano artwork and you did a wonderful job capturing it.
Nice caption XD
I like this shot of your Amano Sephiroth, it shows the shoulder armor and how detailed it is. Also I must say, it is still so hard to believe this is a crossplay, whatever kind of binding technique you used is like magical or something O.O
