Feedback For My Music Video

I have completed my music video and have had some feedback from people in my class, giving their opinions on what iv done well and things I could improve on for my music video.
This is the feedback I got from my class:
Some clips from the music video are quite dark- I didn't realise that this shots were that dark until I put them on to the computer and put them into my video. I would of liked to re-filmed them to get lighter and better quality shots but I didn't have the time to re-shoot as the girls I was using in my video didn't have any spare time as they have college and work. This makes it difficult to re-shoot any shots I wanted to do because I couldn't get them all together at one time or at the times I was free. Also the days get darker early from when I began my redcording so getting home from school and getting to film is hard as I only had an hour before it got dark sometimes even less time. All of this contributed to not being able to re-film certain shots.
Lip syncing out- When I went through my music video I could see that the lip scncing was a bit out but I wanted to get all the video together first just so I knew how many shots I needed. Over time I replaced shots and shortened or made them longer so they would fit in perfectly with the lip scying. This is now noticable in my music video as its sycned perfectly with the song.
Good backgrounds used but some not as good as others- The backgrounds I used were all different as I want each member of the band to have a different style and feel to them. The graffiti background worked very well with Beth as the location was good and the lighting was also good as we shoot outside with the sun on her face. I used a painted background for Alex as I wanted different backgrounds for each girl as this showed their different styles. Alex's background was in my garage where the lighting wasnt the best as I didnt have extra light and wasnt much space to this is why you can see my garage door in some shots but I think it still worked well. My final member of the band I did on a brick wall for her background and this worked well as we were outside with day light but what I didnt realise was that the nights were drawing in and it started to get darker earlier which you can see when you watch this music video. After realising this there wasnt enough time in the day to get a good lighting shot for this particular scene.
Dance moves good idea but some need to be excuded more professionally- I decided to add dance moves in as its a up beat song and a lot of girl bands do a bit of dancing in their videos. The girls learnt the moves on the spot and spent a few minutes practicing to make sure they were insick with each other. Some could have been better excuded by having a bit longer learning the moves but over all I thought they were bright good and I didnt have extra time with the girls because of their schdules.
Drawings dont fit in- I disagree with this statment as they fit in with the chrous of the song "wings are made to fly". My picures so a butterfly spreading its wings and flying. I do have to say if I had more time I would of made the pictures better quality or got them off the interent as they were pretty plain.
Better quality camera shots- After shooting my shots I could see that some shots werent as good quality to others and I did some re-shooting but when it came to doing Beckys shots I couldnt re-do them as hers were outside and it was getting darker earlier so by the time she got to mine and we went to go do the recording it was already getting dark and I didnt have any extra light to make it look brighter and it always wasnt part of my video to make my shots look like this.
Include more letting shots- I took this advice and added extra letting into the video where I thought it best fit. I like this part of my video as its not all scene of the girls it has a bit of a different look to it with the words of the song coming up at different section through the video.
More locations could of been used- I disagree with this comment as I used three different locations and I was going to use a fourth location but when I went to do recording it was raining outside on the green I was going to use for the long shots and dancing moves, so I had to think of something different to do and did it in my garage as it was the only space I could find at the time. I got comments on the garage shots saying they werent very good or professional which I do agree with but I tried a few times to go outside and it just rained everyime so had to go with plan B.
