well, honnestly i think neither one of these really is it.
(i'm about to make a vincent cosplay too)
i have a pivture for you; http://media.giantbomb.com/uploads/0...edcapeback.jpg
look at the back. his cape is made of two pieces. one upper, coming untill halfway his arm, and unterneath it there is a cape from witch the ends are badly damaged. also do not forget about his neck. there is something there too.
(english is, as you might have noticed, not really my language)
it is quite the challenge, but... i'm looking n how to make it too. if i find how, i'll let you know.
