Writing a soundtrack

With only 6 days to go until assessment or should I say judgement day and having clipped together 2 seperate video edits, one in After Effects, the other in Premiere Pro I have moved on to look at the overall soundtrack which I will be creating myself.
I've already made a series of loops using programmes such as FL studio 10 and a basic track in Garage band although I may not use either.
FL studio 10 is a create composer and can pretty much do everything you want. Tricky part is bringing it all together into a soundtrack that fits the film. As I'm working on my own with this it's nearly all being done from memory composition with a few tweaks in Encore at the finish.
