Activity "The object of my affection"

Things I liked:

1. Confidence and liveliness of the whole speech and presentation.
2. Eye contact all the time. I run through the audience lest they get bored or off a subject.
3. The logic of the speech, there wasn't jumps to and fro. The speech is comprehensible enough.

Things I want to improve:

1. To get rid of the sounds of hesitation. While thinking or remembering I'm always saying "eeem". I suppose I am afraid of pauses, but I shouldn't because pauses are not that bad, or it's also possible to learn to say "well","you know" etc.
2. Oh, body language. It seems I flip my hair back all the time, what, I believe, can become peevish during the whole speech.
3. The manner of speaking. I want my spantenious speech and especially prepared to sound vividly and emotively.
