Why I suspect he isn't really the creator of "his" skin and there is copied content from Ryddick's Windows 7 skin:
note: His skin (Ryddick's skin)
Images 4302.png (4302.png), 59004.png (20510.png), 59005.png (20511.png), 59006.png (20512.png), 59007.png (59002.png), 59008.png (59003.png), 59001.png (1908.png), transparente.png (1786.png) are exactly equal, even in byte size AND creation, last acess and modification dates, and have been inserted in the exact same way and order in both skins, even the comment tags are in the same places.
Both have the same mistake right in the begging of the skin info (only <SkinInfo> tag, nothing about schema files as commented in the docs).
