Soh Fan:Your speech is generally clear, but the body language says that you are unprepared, and the background noises such as the basketball bouncing everywhere is kind of distracting. Your fluency is compromised, and sometimes the sound of the basketball blocks out your voice. In my opinion, you can improve by not fidgeting so much, and generally staying still in one position(i see no reason for picking your phone up in the middle><). Using the basketball in the video is a good visual aid for the audience, and allows them to visualise the situation even better. Also, if you were to prepare a little more, the fluency would improve tremendously and the jerky speech would be reduced.
