How does this piece conform to short film codes and conventions; think both in terms of technique?

Our film conforms to the general codes and conventions of short films. It is really short, it’s under 2 minutes yet it doesn’t feel unfinished when you watch it and the plot is strong enough to be that short. As the majority of short films have a low budget, so does ours.  We didn’t have to buy anything for the film and any props/clothes we used were our own. The film didn’t cost anything to make as we just filmed in a park and we used our own props and the schools facilities for the rest of it. We only have two characters in our film as well, a boy and a girl, but you never see the boy properly, just the back of his head so it is basically like there is only one character in the film. The film isn’t really genre specific, it could be a thriller but the majority of the film is quite happy and it is filmed in quite a chatty way so it can’t really be designed as one specific genre.
