Thoughts on my own performance

I think I had a good performance. I prepared my presentation well thanks to Sean's advices. I practiced out load  and so I was comfortable delivering my presentation. During the presentation I was quite confident but one of my  colleague told me that I spoke in a low voice and I moved my hands too much! I tried to speak slowly and clearly and to emphasize key words. In my opinion my presentation was well organized and it had a clear logical structure but my introduction was a bit lacking in details. I made some mistakes in pronunciation, for example "measures" /ˈmeʒə(r)/.
