It's a while back now - in the end I chose a photo from the various (5 or 6?) kimonos that Gackt modelled/designed last year.

I wasn't originally intending to use an eye-patch photo for such a romantic purpose but the kimono with the roses seemed very Valentine already, so I added lots of hearts to give it that over-the-top effect that only Gackt would dare to try! The finished pic is here:
