I made an audio file using Audition that combined the ambient noise of a crowded bar with the sounds of a bartender making drinks. I also added music and a short intro recording.

Nice work, these are some nice sound choices and the mix sounds good. Remember the piece should have a beginning, middle and end, so think of other sounds you can bring in to give it that structure.
