I like that idea a lot… but don’t over animate it… the school idea is awesome. if the canvas is 1920x1080, then the card could be smaller so the title letters could fix. It definitely smaller. No to the squirrel, but maybe you could add the teacher far away like in the middle way between the school and the tank… like she is looking for the missing student or something…
Update:
Oh, add the cel phone on the grass next to the student.
