Singing evaluation for solo performance

In my singing performance  I feel as a whole it went well. In rehearsals leading up tithe song I had tried to add some characterisation to my voice and facial expressions. This is because I spent some time going through the lyrics and pin pointing key events and changed in moves. I showed diverse range of emotions, going from a worry character to a please character when he get what he wants in the song. In the song I feel that my intonation has improved a lot, this was due to my extra rehearsals on note bashing, and this then gave me the confidence during the song, to think about other aspects. I also had good power behind my notes in the parts that I was more confident with, this showed at parts of the song where my volume dropped down, if I wasn't so sure of the notes to hit. To get a better performance next time I would like to spend more time on my song outside of rehearsal, so that I can be become so fermiluar with it and don't need to worry about things on stage and the song can come across more naturally.
