The visual style is decent, the animation is a little clunky, but it works. What threw me off is the moment when the voice acting kicks in. Up until that point, you used facial expression, motion and music to set the mood and tell the story, but the dialogue brought that to an abrupt ending. Perhaps it's because you ran out of time, which I can understand.
Here's a tip: Don't start animating before you have a solid animatic (moving storyboard). With an animatic, you can plan the motion, shots and timing of the film. That way, you know how long it's going to be, and roughly how much work there's left. My teacher always told us to work from stage to stage of completion, in stead of finishing shot after shot: animatic > all key drawings > all breakdowns > all inbetweens > rough backgrounds > colouring > shading > etc. It's better to tell the full story in less detail than to tell only a part of the story.
