Sigh...
I hope that was your own original story. If you're just repeating what happened in the Phoenix Wright game, I'm going to be severely angry. *Hasn't played her copy yet*
Anyway, the story was captivating and kept me interested. But the grammar sucked eggs. Really, next time you need to get someone to do a grammar and spelling check for you. You made so many mistakes it was incredibly rare to see a single block of text without any. Those kinds of details will stand out, especially in a text-based movie like this.
And next time, be sure to make some of your own animations, and don't just rely on the existing sprites. The limited number of poses in the PW game will make this thing boring if you don't spice them up a little. Add some voice acting, stop abruptly cutting off and starting the music, and clean up your grammar. Then make sure you use your own story, and you're good to go. ;)
Good luck. I hope you continue to improve!
