All rights of the character belong to Square Enix of course... but the photography and actual sculpture is the property of some lady in Korea who made this life sized beauty. It took my breath away and was surprised I hadn't seen this before. As far as I know, it may be the only life-sized sculpture of Vincent Valentine. It appears that he is able to move his head too.
Here is a translation of what the creator wrote, thanks to Animama who graciously translated it for us all to understand:
"From 2006, the 6th doll.
A model of a game character I like.
It is 135 cm tall. The eyes light up, and there is a motor to move the head side to side.
I used premier clay and the colors are done with acrylic and gesso paints.
The makeup was done with watercolors and pastels.
The eyes, wig, clothing, stand and props are all made by myself."
