Looks like the Ronin samural got some weapon and armor upgrades, this piece is incredible as always with your realistic skill with the appearance and detail and creativity with the armor platings, Radio contacting helmet and I noticed he's also holding a submachine gun on his left arm and he has an armor plate attached to his elbow that's a real good piece for him to be resistant to oncoming bullets.
Not bad, but those armor paddings look like solar panels. Unless they have some specific function, should've gone with the traditional stacked, curved plating like in the old style samurais where it was meant to have blows slide off instead of flat plating where it would take the full brunt of it. While flat plating does cover more it makes maneuverability slightly more difficult since they don't bend with the wearer. It's good for shields but only if it's thick enough, otherwise a strong enough piercing attack can drill right through it.
i think thats a bit to much of historical solution. he mite be killing you with his sword but he wouldn't really be attacked by a swords more projectiles, hence the scales down projectiles, well that was my thinking at least
