I've got a pretty literal interpretation of Siegfried's what-the-hell-am-I-looking-at sprite here. It's definitely not the battle one, down to which eye is showing and which arm isn't covered; which is weird, it makes me think the battle sprites are designed facing the same way as your party but flipped, since every solider in the game is left-handed (Almost every soldier). Anyway, Siegfried's battle sprite is interesting because it reminds me a lot of Vincent...?? If you don't know what I mean (and I'll have to explain it because I didn't draw it), his head is wrapped up in cloth, his armor makes one of his arms look robotic, his other arm that's holding his gun has a sleeve rolled up to the elbow and the hand has a glove on it, there's the cape of course, and it's pretty hard to tell but his feet miiiight be pointy. There's a Siegfried costume in Lightning Returns (Oh god, the references have come to this) that has pointy feet, so I wouldn't put it past it. It's all 'interesting' because I see no reference to it in any Wikis and nobody has pointed it out to me before!
