Three things I would like to improve as a presenter - Kiang Jia Ming Kenneth (17)

1. I would like to improve on my hand gestures. I am able to do hand gestures, but they are repetitive or sometimes I do too many.
2. I want to change my tone, because I heard from my friends that I am not enthusiastic enough.
3. I want to be calmer during presentations, as sometimes I may stutter and feel nervous.
