Some changes in speed and timing between the different pieces would fix the tween-y feel.
Add some screenshake and you could also hide the smooth tween-y feel.
Judging by the animations and art, I'd say marquet knows his stuff, I want to play this, it looks great!

(assuming you're looking for critique) The one thing I'd have to point out is the contrast and detail level for the backgrounds, which overpowers everything else and makes the depth unclear.
