Work on it.
Well.. yes. Well done on your first animation.
There are various strengths and weaknesses here. There are obvious things you clean up, like the animation, and the text, but your voice is fantastic for animations and the audio is well recorded. Your humour is also mildly entertaining. I'd like to see you work on this, keep practicing and such. I don't doubt that you have the potential to make much better submissions than this if you keep at it.
