Uhh...not to argue Senn, but you are complaining that Miqo are too built to be 'cute' but...also acknowledge that male Viera will almost definitely be just as if not more built...? so, like, then they won't be 'cute' either.

Also for what it's worth, I'd say it's be the mannerisms and body language that make anyone look masculine/feminine, not their body type - Look at the female Viera, some people are calling them masculine just because they're too serious to act kawaii and are tall /shrug
