I will absolutely agree with :-
1. Good looking entire in term of what you wear which is nice to see.
2. Body language, it help your message that you want to deliver reach to the audiences effectively. Besides, a good eye contact with the audience and always smile like zulfaiz did in his presentation. Nice!!
3. Dont directly read from your slides because it will make your sound become monotonous tone.
4. Clear voice and pronouncement, it will ensure your audience understand what you are saying
5. Design of your slide shows also play an important role to make your presentation more attractive. Use soft color and not to messy and simple but nice to see.
6. Just be cool and chill while you start your presentation because it will continuously develop your level of confident.
That's all for now.........................='>
