Well, got to be honest, I didn't like it that much. It is great to see 3D animation here on newgrounds, but for me it was really distracting, probably because of the way characters moved. It was like they were walking on the clouds. No sense of gravity.
Other thing is that I didn't feel any emotion watching this. It wouldn't bother me that much if it wasn't obvious that you were going for emotional story. My opinion. I could be wrong about it.
I'm sorry, but nothing clicked here with me. It probably has a potential as a live action short movie with voices, but as it is, for me, it falls flat.
With all that said, I encourage you to continue 3D animation. I am really interested how much you can achieve in 3D ;)
