Improvements
To improve my work I have listened to the songs in my spare time and tried to learn the structure. I have learned the structure for the first song and nearly the second song and I have just started the third song but I have a pretty good idea of the order of it.
For the 1st and 3rd song I need to know when the drums come in and out and I need to learn the drum structure. I could also try add some drum fills to make it more interesting rather than just it being a simple beat all the way through but that will come with confidence.
I could also improve my posture while performing but sitting up straight and making eye contact with the crowd and some band members. This will make the performance look more professional.
