informal speech

In my informal speech I feel like I got the attention of my peers with my opening statement. With that i think they became more interested in the topic and I kept their attention most of the time. Thing i think that I did well was eye contact, spoke clear, and stayed on topic. Of course i said uhhhhhh and and uhm about 20 times and i havent found a way around not saying that yet. according to brandon i said it 19 times. I thought that my information was good and stated what needed to be known and more. My conclusion was the classic "well thats it". i feel like i can come up with a better ending statement.
