Laughed almost every time his friends showed up. Liked that comedic touch.
I agree with the moral/message, but it felt a bit cheap that a few words and the telling off of seemingly random bullies(not even though. Just guys being stupid. It doesn't seem like targeted bullying) convinced her to have some more confidence. I would expect a little deeper look into her life for those confidence issues. Maybe use some bullies that are girls and have known her for a while instead.
Art is solid. It didn't amaze me, but the tour of all the different "attractive" girls in the school was entertaining and certainly on the better looking side.
MC is pretty forgettable because even though I see clear signs of effort, my image of him still boils down to "the fisherman's son who takes photos". Not sure what would make him more memorable.
