Editing the thriller

Finally today on the 29th march we have finally finished editing our thriller we only now need to make sure the music is is more sync with what's going on in the picture, in total after all of the editing we have done there is 3minutes and 50 seconds of footage, but is still quite long and may need tweaking or cutting down depending on what the rules are, i feel like our thriller is suitable for all age groups and Theres no specific genre we have made it towards.
