Video animation

I want a 60 seconds Animation video I don't need VO (voice over) and I don't need music (unless you think it's easier to show emotion). but to me it's ok, without sounds --- regarding the character, the main character is the most important, he has to be likeable and relatable. the rest is kind of background. Only 1 extra is completely necessary (his teacher giving him the book) --- the rest is background, for example, scene 1 is in the tram. the focus of the scene is our main character.. there is no need to focus anything else, but you can add some extra models in the background if you think the scene will be better, but there is no need, if you angle the camera, maybe it will be ok with only 1.. --- 2nd scene is in the classroom, so we have our protagonist, his teacher, as the main and secondary, and maybe a 3rd (student/friend), if you put the protagonist in front roll, near the teacher, maybe you don't have to load the other models. --- therefore from my opinion, I need 1 main character, 1 quick character (teacher). the rest (like other students) are background, they don't need to focus on expressions, etc. but it's up to you. --- So kindly check the file below for the full script of the project
