Wow. This is fantastic. Great detail on the costume, deep facial expression on the model, and taken by a good photographer. However my theory for his sad expression is that he is a very underrated character and Cloud gets all the attention. Obviously poor Vincent is wayyyy more badass!
Just while I was scrolling to the bottom of the page to see a bunch of the Daily Deviations I saw the thumbnail for this. I stopped for a second and said "Is that... Oh my Gosh it is" and then started fangirling. Made my day and I didn't even expect it. Amazing cosplay, and congrats for the much deserved DD! ^_^
