Evaluation of Prelim shoot - Shooting my first Scene

We hadn't the time to build a setting, so we just used what already has been there: The room, we were supposed to work in, two chairs and a desk with a computer. We opened a window in the computer, which looked like a typical hacker/matrix window to create a little thriller atmosphere. 
We built up the tripod, did the bubbling and put the camera on the tripod. Than we set the white balance with a piece of paper.
The first shoot we did was a short shot of a piece of paper with our names written on, to be able to find our shots later.     
The sequences, we shot, were the shots, which were set by the task.
We started to film the scene a few times in wide shots from different perspectives. Than we slowly went closer with middle and over the shoulder shots to film the duologue between the two persons. After that we did the close shots of faces.
During this shots the actors (Flora and me) did the acting as well as we thought how to position camera and tripod with the other two members of the group (Vinnie and Liv).
After we finished the shots, we had to film, we started to add creative shots like a close up of the computers screen and the "matrix code", other close ups and middle shots of the actors from different perspectives during the duologue and different shots of me running up and down the steps in the staircase.
During these sequences not every actor had to be on screen and so the actors also worked as camera-man/woman.
Although we all thought and discussed together how to film the sequences, everybody also had his tight job:
Liv was the director, Vinnie was the camera-man and Flora and I were the actors. 
We hadn't any big problems during the shooting, but one thing was quiet annoying. And that was the tripod. We couldn't position the tripod close to the chairs or to the banister of the staircase, because its legs were in the way. 
I think we worked good as a group, because everybody brought ideas in and thought about how to shoot this scene. Everybody had his job and we hadn't had any problems between each other. Every idea were tried out. There are two things we should do better next time:
First:
Vinnie and I did the most, because we wanted to work with the camera and try different angles and shots, but we didn't include the girls enough. We, and specially me, need to do that next time.
And second:
We didn't work with a good plan. We just jumped from shot to shot without thinking about the hole product we want to produce. Next time we should work with a better planning.
But it was , all in all, a very good first shooting experience and I'm really looking forward to get more of this experience to improve my filming and team-work skills.
