Please oh please tell me that you're going to work more on this. The background art is beautiful and the concept is really nice. But the animation is so rough and choppy and animatic-like, it sort of ruins the prettiness of it.
Just a little more smoothness, a few more frames to add some detail to the movement would make this a million times better. Like a few leaves on the trees rustling, a few fframes more on the dogs wagging their tails, etc. I can see you've already put loads of time into this, but it'd be so worth putting a bit more in to see it through to the end.
