A breath of fresh air!
Nice work, man. It's refreshing to see some animation that doesn't rely on fart, gay or DBZ related sources to tell a story. Unfortunately, I had to give you an "eight" for two reasons: One, the issue with the voices going out of sync with the characters when they were talking especially towards the end; and two would be the use of photograph picture backgrounds in the beginning of the movie. It came off bit a strange.
I know drawing city landscapes can be difficult but it's better than using photos because it melds much better with hand drawn animation. But anyway, good job.
