Sound

So I have been working on my sound for ages and have been trying to think of a song to play in the background. I asked my friends and they told me to use a song that they would sing. So I asked them if they would actually want to sing in my video and they aggreeed so we went out side to recored it. Meghna, Izzy and Sarah were singing and we were trying out different vocal sounds so that they sound like a man. They also sang individually, and in the end i chose to use Sarah's recording because it actually sounded like a man. When I put it with my video, I found that the song was too long for the part that i wanted it to play for, so I had to edit it by cutting out the last bit, and it sounds really good! I have also found a burping sound for the fish and footsteps for the man when he is walking. I do not know if I am going to use the footsteps though. I have to make that decision later. I have also found a chomping sound for when the fish eats the man. When I play it back, it looks and sounds really good, except that I do not know if I want to add any other sounds in the silent areas. Does it sound like an awkward silence? Or does it sound good? I will have to ask my friends and find out!
