From someone who was a dedicated ninja freak 15 years ago (damn i'm gettin old), all I can see changing would be the sword to something that looks Japanese (and a better mask)... I personally would love to have a good model of a katana, seen a few out there but the ones i downloaded sure wouldn't fool someone who knows what one really looks like. I remember someone posting a suit of samurai armor and acessories they were working on, but that was back last summer...looked quite good.
