Needs work, but not bad.
~ Animation/Graphics ~
Pretty good animation and drawing style that you have here. I think I would recommend doing some background work here. Perhaps just outside with the green grass, tree in the background, perhaps something slowly moving in the background like someone walking, while they are blurred out a little to represent being far away and hard to see.
~ Story/Content ~
Woo.. a very short animation. Ha, well I recommend making it longer, but since you probably want to leave it short I'll try to say how to improve without making it much longer. I think it would be better if you had more of a delay in the beginning. Nice peaceful background with birds flying by. Nice day outside and everything, and then all of a sudden the two run into each other. That way it's just not so sudden and there is a nice little build up effect.
~ Audio ~
The voices were ok, but the quality did sound a little poor. Not too bad though. I think it would have been cool if you used the delay in the beginning like I recommended and had the voices sound like they were coming from far away and then get slightly louder as they got closer. Also, since I think this really needed background stuff that it wouldn't have been bad to have things like birds chirping, wind blowing, etc..
~ Overall ~
The things that I recommended are completely up to you, but it's what I envision when thinking about how to make this better. Keep up the good work and good luck on future projects.
