In the first workshop, I did not get the chance to present my arrangement but I did however get to listen to about 7-8 students present their arrangement which lead me to revise my own draft.
Although I had an idea of where I wanted my improvisation section to be, I hadn't notated it in the score yet.
I also realised that my advanced and simplified versions were probably too similar (ie. my simplified versions were probably too hard) so I will need to revise those before the next workshop where I would present my draft.
