Hey, this looks like an awesome project, so I'd like to contribute.
I just made a small Link animation where Link's left hand is on his waist and his right is hanging off to the side. (he breathes in it; he's not just still)
Oh, and make sure you use it in Brawl, not BrawlBox, because Link has some unknown tendencies to do certain things that aren't in the animation (in Brawl), so it looks weirder in BrawlBox due to fixing those problems.
Here're the downloads: (Use both the FitLinkMotionEtc.pac and the FitLink.pac for it to work)
Click hereI've been through the trial and errors of it, so it works well for me. If anyone finds kinks in it or anything, just contact me about it.
