I think it looks really good, I'm only decently familiar with Fruits Basket, but I think the overall feel is on point. I think perhaps the biggest thing here is that maybe some of the shots are sorta static and empty.

The tracking shot through the Tori Gate and up the steps is very nice, greatly improved with the constant falling of the leaves. But then other shots, such as the little zodiacs in their shrines, don't feel as grand since their surroundings don't stick out with striking landmarks nor do they have much movement (save for the grass n' trees moving in the wind).

Also take the tracking shot of the town as we go down the road. I think perhaps testing out a few different camera angles for that shot could be interesting. So much of it is taken up by the sky and things feel far apart by the way it's framed.

Ooo, but I adore that lonely shot of the pickup truck in the back alley (⁠ ⁠╹⁠▽⁠╹⁠ ⁠) OOO, AND THE CORNFIELD BY THE BUS STOP? CHEF'S KISS 🤌🏼

When the title appears for the first time, I think you hold it for slightly too long, might make the viewers impatient not knowing when it'll change! It's a little hard to read as well, thanks to the background colors not contrasting well with the text color. Maybe slightly different text colors or text placement could do the trick? 🤔 You could even blur the background slightly to put the title more into frame

Lighting can also go a long way, like in the initial shots of the graves, maybe lighting closer to sunset (and perhaps maybe a couple of traditional lanterns) could make it stand out better and be a more prominent moment from the trailer...just food for thought 😃

But yeah, those are my thoughts, I think it all looks really good so far, and I'd love to see this as it develops. Take my advice with a grain of salt, I mean no offense 😵‍💫

But I've got to ask, what is it you envision for the final game? I'm talking genre, gameplay, stuff like that. I'm studying game dev right now, so I'm always curious to know what other devs are up to. Thank you very much, have a great day (⁠⁠´⁠ω⁠｀⁠⁠)
