who?

A friend of mine went to the pain of making me a birthday graphic and, being foreign to the fandom, picked up what he deemed was a suitable picture. I'm moved by the effort but the thing is, I can't quite place who the 'sienne in the picture is!

So, anybody knows? I first thought it was Yamato Yuuga but I can't be sure...

Thank you!
