You have a point, but I think it tends to look weirder when caucasians try to cosplay asian characters than vice-versa - especially when it's one of the key characteristics like Tseng or the demi-fiend, _and_ it's crossplay. And it's less I'm saying nobody should do it as much as that it just looks bad on me, much in the same way that I wouldn't try cosplaying Sakura from CCS because I am not a tiny cute ten-year-old girl.
