Thank you everyone for your feedback! It would appear that all of you liked it very much (one of you loved!) with some very minor suggestions [some context to explain one part with students and I myself noticed one or two minor audio-transition errors, both of which I have fixed]. As mentioned, some exclusions were intentional such as not placing any subtitles in some sections.
I appreciate your responses as this is my first film and I seek only to perform well enough to fundraise for the school. I am now planning my next one and hopefully I will avoid all the difficulties I experienced in this one!
