So far, one thing that's really just jarring to me is the 2d sprites and 3d backgrounds. I'd also really recommend working on that text box and please. This does have some potential, but it's really jarring for the sprites and the background to be two different ways. Also, the lack of music is killing me. Even if it's just "test" tracks, I'd find something you could borrow to portray a mood. Or sfx you could use:
* Cafe sounds - People talking or a light wind
* Library - Clock ticking
It seems good but it has a lot of room to grow.
