This came off as very real to me. My brother struggled with grades too. I admit it did get kind of too silly at the end. It suddenly seemed like an action anime. I appreciate the animation of course. It was weird to end with drawing Zuko.
Still, it's a nice drawing. The grades were higher when I was younger. Good thing I was a good student! I don't mean to degrade you. Exaggerated, but still great.
