Criticism of our idea

After pitching our idea to our peers and teacher, we had some constructive criticism from everyone. A few things they said to take into account are : - is there enough material for 3 minutes? - is the location good enough? - needs to be a sub narrative So after much deliberation, we decided to add a sub narrative of having several girls coming to audition to be the model for the artist, but the artist just doesn't seem to think they make the cut. He then meets our main girl (blonde girl - Rachel) and falls head over heals for her. Due to this sub narrative, we feel we would have enough material for 3 minutes and also keep the audience captivated.
