AD on a whole film? Wow, I'm impressed!
Strange that on the one hand you seem to be quoting your tutor as a definitive expert on filmmaking and on the other hand you seem to be ignoring him completely. Of the 3 apparently "most important things in a film" how good was the acting in your film and how good was the location? The last of the 3, the story, I couldn't judge/critique because the other two "most important things", plus just about all the other apparently not so important "things" were all so poorly executed it was impossible to tell!
So in fact you lied when you said that "any feedback would be hugely appreciated"? Although the contributors to this thread may have been a little harsh (including me), they've nevertheless given you some usable information and for that you should be grateful rather than so defensive. The professional film world is far harsher than we've been, if you're not capable of taking a bit of harsh criticism maybe you're aiming at the wrong profession?
