Good effort
I can see that some good effort was put into this, and the character graphics were definitely good. Some things to work on are to: stand away from the microphone, it kinda sounds like your a little too close to it. Also, a good way to make your voice deeper is to try an imitation, then download a program to adjust your voice in its pitch. This way, you can characterize characters with their voice, and not all sound is monotonus. Nice style, keep up the good work!
