After viewing my speech a few times I have come to a couple conclusions...
The first and most obvious is that when I talk I need to SLOW DOWN. Even I had trouble understanding some of what I was saying. I think this could have been helped with both more practice and taking a deep breath before my speech.
The second thing I noticed was my posture. While I stood in one place during my speech I looked like a flamingo.... One leg was almost off the ground.
While watching myself speak, I noticed I made a good effort towards eye contact and hand gestures, but more practice and planning will help those things seem more natural in the future and to make sure I was not just looking at a few students in front of my, but the entire, "U" shaped room.
I think my speech was structured well. I used my simplest explanation first and saved my more complicated one for the end once I had introduced the audience to my topic thoroughly.
Over all I think my speech was okay. I am happy with the points I made and how I structured things, I just think a bit more practice before next time could help hammer down some of the speech skills that are important besides the content.
On a scale of 1-10 I would give my speech an 8.
