Suzaku, this is amazing. Just to compare what you did with Guilty Gear XX versions of Sin and Bedman made by RieyTails (yes I'm aware of the huge size difference, but I think it's still worth a comparison, quality speaking that is):

With editing and maybe a palette change (or resize, if you want to go further, but I don't think that's necessary), it could look truly XX official. So thanks for the share, Suzaku!
