As in some other discussions, the rubber like texture just feels off. Personally the cape is a turn off. The ring though is gorgeous, without the backpack object.

In traditional displays of the Raijin, the ring comes from the lower back and is larger, framing the body more than just the head. As this is a great concept to capture the Raijin's design, it'd be nice to see the scale of the taiko increased with stronger energy effects.

So, personally, drop the backpack and cape and focus on the ring and taiko to capture the feel of the Raijin. So happy to see the theme coming to this game, kinda tired of capes haha.
