The improvements are excellent to see. Wonder if he can crunch a bit lower/wider for the Chidori charge. Looks good as it is, but a little more would be perfect.
I like the eyes. Though they still have that sort of coked out look to them, heh. The original prototype probably has set eyes, so it looked more true to anime/illustration, but the newer version has a nice depth to it + the Sharingan glow.
Glad to see the waist swivel is a real thing... I just assumed it was always a thing until my Masamune broke. Fortunately my Sephiroth GT didn't from the same thing.
I do hope they will send spare eyes or something for Itachi if there are clear improvements to the glow. Seems like an unfortunate thing to be early but no way to get the improved spec.
