One of the things I kinda hate of the original is how different the CGs are compared to the sprites. It doesn't need to be the same, the sprites usually have more quality, but when the artist style is absurdly different from one set of art styles to the other it became quite jarring to look at them.
I'm not oposed to you all using what works on the original, I would like to see certain routes getting more love compared to the original, for example Kouya's route is one of the most simple ones since it was one of the first finished ones. If you're going to add three endings for other routes, just do it for all of them XD.
I can't wait to see the entire cast with the new art style though. Good work guys.
