Character models are nice, but they tend to be over animated, specially when you can move the dialogue forward faster than the animations themselves. And even if nothing's happening, some of them just wiggle too much in general, so I'd say to take it down a notch.
Also, the general UI feels pretty bad in general, the text is unfocused and sharply contrasts the char models in a bad way, and the extreme blurriness of the backgrounds doesnt help either.
Im not sure where exactly do you wanna go with this, but if you really wanna give the 3D model focus then you'd benefit greatly from making 3D environments as well, and using more interesting chamera angles than just "looking in front of you, and everything else spins around". Maybe its just me, but there are a lot of times when the illusion of space just isnt there.
RE_POST: Sorry, I deleted the previous comment because I forgot to mention, please please PLEASE add proper KB support, please, even if its just for the dialog options.
