They aren't likely to be picked to appear in perfume adverts (which usually feature pixie-faced waifs), but no, they don't seem to be masculine. I wouldn't object to some 'dainty' faces, but I don't have any problems with those featured.
Actually, a couple of faces who looked liked they have more than the usual amount of testosterone would actually be a welcome addition. A solid muscle-bound fighter or, when implemented, barbarian, could have a face that is more heavy-jawed and masculine than the current options.
