From Season 1 to Season 2 we have seen a huge visual change from a very rustic, raw, metal look, to a very polished technological and even somewhat child friendly appearance, with plenty of colour and contrast.
In Season 3 I would like to see a change back to the old art style of everything being rustic, metal, violent, and brutal, as opposed to the more clean look season 2 brought. I think that this more aggressive style is more KI, as it is gritty and dirty just like the gameplay (speaking in terms of art and style, such as the animations, and not the actual mentality of the combat).
I would also like to see a bit more of a darker tone to the menus and a more violently energetic announcer, as well as more brutal sound effects. (This isn’t to say to re-do the sound effects but rather to rebalance them)
Even some animations could use a bit of touching up, to remove some of the “Goofy-ness” to KI but retain the aggressive raw edge, more so seen in the EVO build of KI, when it was just Jago, Wulf, and Glacius.
