This is an EXCELLENT cosplay. The costume is pretty faithful to the character - not to mention, it's pretty detailed. It looks quite well made, too. The hair, too, is really faithful to Cloud. That's actually what struck me first about this cosplay, the fact that the hair is very VERY Cloud-spikey, getting about as Cloud-y as one can without outright defying gravity. I'm impressed.
From a photographic point of view, this is a cool picture. The setting is really interesting wit hall the grating, and the pose fills up the frame and causes movement. That's also a pretty intense stare you've got there.
