the sword is dumb, but it is sephiroth, so w/e
i personally loved FF7 more than any game, but i hated the character art direction. the costumes were cool, the style was crap. still though, in game, the only reason for the small torso is to make room for the big head. i think even in fanart, proper propotions still stand. the art for ff7 was some of the worst, and id advise against emulating it. costumes good, characters good, proportions? use ones that make sense.
