Feedback for Film Draft

I've recieved my grades and feedback for my first film draft

For my research and planning, i got a level 3 (proficiency level) which actually rather surprised me as normally, my research and planning is not the best part of my work.

And unfortunately i got a level 1 for my film (Minimal Level) which i was very disappointed with as i've had this sort of horror film idea in my mind since i was first told about doing a film for my coursework. However i can see why my grade might be low on a few different things.
Many different parts of my film were changed due to time, location and casting. The only people who i had that could star in my film were often busy with their school work, and quite often one of us was not able to do it on the night planned. In the end i had to try and get film redone during the last 2 media lessons before the deadline. Because of this i had to use the school itself as the setting for my film, so had change quite a bit to make it fit around the school. Unfortunately, because you ca easily tell its a school, it adds a bit of humour to the film that i really do not want as it disrupts the sense of panic and fear. Also i only had 2 people starring in the film, when my original plan starred 3. Also because of the lack of time caused, i never managed to get some music recorded for my film and had to rely on copyrighted music, just to at least show what sort of effect i want the music to cause.

Even with my first attempt of my film draft, many things were wrong. For starters, because it was recorded during school hours as well, the location i wanted to use was being used as a workplace car park, so i had to film in another location. I think that if i had managed to use my original location, it would have turned out better. Plus i didnt realise that i had to actually do the filming of my film, and not star in the film itself (which i was kind of glad about as my original camera man kept using zooming when i didnt want any zooming going on as it just looks really tacky)
Another thing i didn't like about my first draft was that i played around with some dialogue which, to me, just really didnt work.

However my teacher did say that he really likes some of the shot that i've used in my film, such as the attack scenes, and that the music i chose actually went well with film, just a shame that the music was copyrighted.
