First Speech Compared To Last Speech

I really did not see that much improvement from my first informative speech to my last persuasive speech. I still didn't have that much eye contact in my persuasive speech. I spent most of my time looking at my power point on the computer. In fact I might have had more eye contact in my informative speech. My introduction and attention-getter improved a lot from my first speech to my last. In my first speech I just told the audience what I was going to inform them about but in my last speech I ask the audience a question, therefore getting their attention. I still didn't put any research citations in my last speech or in any of my other speeches. My conclusion in my last speech was very weak compared to my conclusion in my first speech. My volume improved a little from the first speech that I presented and I also had more enthusiasm in my last speech. I had very little hand gestures and still need to improve on that. I could also use a few more voice pauses in my speech. In conclusion I improved a little throughout my speeches but still have a lot more to improve on.
