I'm not sure exactly why this is so hard to follow, but it is indeed. Some is because your drawings are UNFINISHED. It's not that they're "imperfect", they're unfinished, buddy. The music is completely inappropriate and it moves ridiculously slowly with all of your slideshow motion tweens. There's no action! No movement!
You NEVER put the words "narrating" in a speech bubble! I don't even know why you HAVE speech bubbles. Why? What are they for? For the deaf viewers? Okay.
Your spelling/grammar is poor.
Good scanning and recording quality. I'd like to mention, though, that the teacher sounds ridiculous. She sounds she's in porn.
Your use of story elements is promising, but you seriously need to work on your entertainment factor. Maybe study some animations. Even your dialogue was way off.
