Maybe when you are in your 30's but the guy is 60 and looks it IMO, look at about 59 seconds in when he first walks away from the house to go fight, he looks like an old lady afraid she's going to get mugged lol.
I think he looks great lol
The only thing I'd like more would be the OG ninja costume from MK1 and he would be complete... Although you might have a point regarding age there, I'm not sure how muscular his arms are at this point but if they look old maybe that would look bad with the classic outfit idk.
