Before I get to the review, I will say that I find it coincidental that I find this in the top 5 right after having a conversation with a few friends about the series after showing her that KH 1.5 Remix came out.
Anyway, on to the review.
There are many things about this that shows that you're on the right track but there are somethings that don't feel right. First off, I think you can do without using moving pictures all the time. It usually ruins the quality of your animation. Secondly there were some jokes that just didn't make any sense like Sora turns into a chicken right after being beaten up with Leon and why's Selphie on the bed looking normal?
The voice acting is good though. That's the closest thing to KH 1 that I've seen so far. The others were good but some had terrible quality mic.
Also, you might want to try improving a bit more in your art style and animation.
