I don't hate any of the races, all of them have issues with how they look in my opinion.
Midlander male: Can look like a babyface teen, really annoying to see them (especially as tanks lol).
--- female: Their normal run animation... I hate how they swing their arms in a stereotypical "girly" fashion (reminds me of Vanille in XIII, just less eccentric, which is a good thing).
Highlander male: A bit too burly for my taste.
--- female: nothing really wrong here =p
Elezen male: As others stated, the way they run.
--- female: Shoulders look very broad. It just looks strange to me, especially when wearing tank armors with pauldrons. Also reminds me of some drawings I did in the past, where the proportions were off. Other than that I think they look fine ;D lol
Lala male: Head size compared to body. No complaints really, proportions make waaaay more sense than Tarutarus.
--- female: Same as male, one complaint I recall seeing in posts in the past was about their breast slider "not working"... lol.
Manthra: Rigormortis in hands, cat ears bug me. Standing stance is a bit weird as well (I realize I main a male miqo'te, kinda wish I stuck to my original midlander look).
Mithra: Dislike the shape of their heads, looks strange to me. Maybe it was an "ideal" shape or something, idk.
Tailless Galka: The upper body and lower body proportions bug me.
Female Roe: Some of the noses look strange, but otherwise no issues really. Though bust size can be ridiculous (goes for highlanders as well).
