The question of Terra's hair also gets more complicated when looking at Dissidia's version of her (the blonde) and her Threarhythm version (green). It's like they're deliberately addressing sprite and normal-proportion differences (but then Faris got slapped with blonde hair instead of her purple).
Ok, I never played Dissidia, but...
I know Terra had white and green hair because of alt costumes. Did they not do something similar for Faris? (would seem logical)
While we're talking about the artwork discrepancies: was there any reason for the vast differences seen in Celes' bathing suit & cape sprite and her yellow-spandex Amano outfit? That one weirds me out the most.
First 3 costumes are based on relevant official art (#1
)... and then there's the last one which seems to come out of nowhere.http://fc08.deviantart.net/fs70/f/2012/153/e/6/dissidia__celes_chere_costumes_by_isaiahjordan-d51zejn.png
