I really liked the colors and character design. I think the motion was solid, but could have been a little more active. The subtle shake was kind of cool, but I think some blinking and a little movement from backgrounds characters would have helped the animation feel more alive. The sound was a little annoying. The high frequency stuff was a little too much at times, but it wasn't too bad.
As far as voice acting, I think one character could have been better. It seemed like the teacher was supposed to be a redneck, but the voice actress couldn't really pull it off. I feel like if she went way overboard with the accent it would have been funnier than underselling the accent.
The script came off a little lazy. After the teacher starts talking about white history and the kid talks about shooting up the school, the story becomes all too predictable. I think some shock value or a twist would have really helped make the animation more entertaining. Overall, its not bad. I'm digging your art style and look forward to seeing more of your stuff, m80.
