Your post is very nice. The video captures the atmosphere of the college and especially the corridor scenes of the mathematics department very well. Wide, medium and close-up shots are also well organized and the storytelling feels natural. I think if the lighting or camera stabilization could be improved a bit, the video would look more professional. Also, including a few small details or moments of student activity can add to the vividness of the story. However, the entire post shows how deep your feelings and memories are for your college,It was a pleasure to see that. Really an interesting and educational video.
