Wow! This is a great little piece, and indeed, beautiful. Congrats on this work. I hope you're entering it in as many festivals as you can. I'm gonna go on record as saying whatever trajectory you need to take to get this in front of an Oscar animated short panel, do it.
Couple suggestions:
I think the opening pan/zoom into house could be continued during the transition to inside. Some of the frames you repeated for the closeup of bird and woman's face at end might flow better with more varied frames. I don't think it would be too much more work to draw out 5-10 frames for each.
