You have a very clear framwork in your introduction. You use a lot of signpost words. You also involve the audience. You have your own style of speaking (it's cute,I think)Anyway, I think you can make your presentation better if next time you can speak more naturally, try to be relax and make a little more tonation and emphasis during your talk. (plus, a bit louder voice too)
I think that the audience is involved in a good way, it will be better if your voice is louder and you change tone of your voice during the presentation.
Feedback is coming. You've got cute voice in which I can hardly find any drawbacks.See you on Thursday
A cute girl with cute voice. The introduction is very interesting and the structure is clear to me. I like it! Wish you be braver on Thursday and good luck!
