Organisation: First trailer draft and Feedback received.

I have received feedback from the first draft of my trailer. My teacher has given me constructive criticism to improve the trailer. Firstly, the positives is that:

• In terms of technical codes, overall he gets it. 
• Its very promising and has potential.
• The story is obvious domestic happiness, disrupted by the 'other' woman and then a revenge story.

However, to improve he has suggested that:

• It needs tightening up and its too long. 
• He feels like too much story line has given too much in the trailer, what is left for the audience to find out. 
• The strongest part is definitely from 1:05 and towards 2:58 onwards the trailer loses it, so he recommends cutting the trailer and finishing around 2:53 as the other scenes starts to lose the just of the trailer and becomes a bit tedious, and remove the gun and the fighting scene and just finish the trailer of with the blood splatter.
• I have used too much existing music when your only allowed 13-14 seconds of original music, so I need to remove some of the music.
• At the start of the trailer which shows the relationship of the loving and doting couple the dialogue/ sequence is on the border of the genre RomCom. He suggest keeps the sequences shorter and (flashed), lose the dialogue and keep the music. 
• Don't include the MGM inter-title as it does not exist anymore and does not relate to my production company. 
• Remove the poster like ending and include a credits which is usually what trailers end in. 

I will listen to this feedback and re edit my draft and incorporate this into my final edit so my trailer will appear more realistic and professional.
