Thanks for your comment.Lock of time made me finish it too early. About the fly sound ,i choose it on purpose, that's my way to described the invasion . They came like bugs . by the way i really like your movie. it's very funny 

I kept trying to swat the flies that were buzzing me while I watched this film, until I realised it was the sound of the ships flying by! Best of luck in the contest!
