I already changed the hair for a better model:
As for the eyes, I kinda agree when looking at them like that but I dunno, that's how they're posed in the original game, actually. (ie I didn't change anything in the x axis, the eye models are already made to be this far apart)
Also, whenever I convert a snapshot it looks squished. I mean, Falcon isn't supposed to be that small, dang it
And if I narrow the eyes, it means changing the rotations so it doesn't look awkward as hell through trial and error(since animations don't show up in CollisionDatas), and more importantly changing the eyebrows, which are one model, with one bone and actually just use a brown square for a texture.
tl;dr: Haruhi Wii has nice models but god are they a pain to get posed correctly. Did I mention that animating them is also incredibly annoying? X) bones aren't linked so moving one stretches the model
