Need to Improve Audio
This is a great animated series. I know that some folks on NG have said it is unoriginal but who cares. I know you are having a great time working on these movies. My only criticism is with the music and the voices. You need to slow down the dialogue. It is hard to get into the characters when their lines are spoken so fast. You may want to think about your background music as well. You music should set the tone but not interfere with enjoying the movie.
Other then these two minor things you have a great series going. Keep up the good work.
