This looks pretty good! Few things. Firstly the Sound design is a bit off. It needs better folley. Just out right needs meater sound effects to add that oomf, Also Timing is another thing that needs work. You want to make the hits FEEL like they connect, imagine a you are playing a fighting game and you whiff an attack appose to an attack making contact, you can feel the difference and see it. And finally Lip syncing is WAY off. i get doing the Anime lip flaps, hell I use them in my current projects now, it's easier and gives it that anime feel, but it needs to be synced up. Not to mention the VA's kind of feel like they are just recording with out Visuals, or context so it sounds a bit off.
But Visually, it looks stunning, the art style and the compositing is on point. Just needs Better Sound design, some re-timing, another pass on Voices, and proper lip syncing and this would be absolutely PERFECT.
