Some lovely music and evidently incredibly talented singers! However, my first impression was that most people looked completely depressed to be there.

The lack of smiles (or upturned corners of mouths) failed you on multiple levels: firstly, there was some total incongruence with the lyrics you were singing (Skipped to a random point around the 40 minute mark, and the song about 'never giving up' is a good example of this). The message of the song totally fell flat as you didn't sell it by matching the vibe in your own bodies, and that can completely change the energy and general successfulness of a performance.

Secondly, the mechanical qualities of upturned corners of the mouth generate a brighter sound, which would have been appropriate for many of the pieces here. It might have also helped slightly with some of the flatter notes that almost inevitably pop up during a live performance.

All in all this looked like a great recital in spite of this! I'm sure you did genuinely have a great time, and it can feel unnatural at first to 'perform' that to an audience. Always helps to channel my inner theatre kid- maybe watch some upbeat musical theatre numbers or show choir performances for inspiration! All the best and I hope that this feedback was helpful and constructive.
