one suggestion about layout of presentation -

Some nice tips of having presentation

Do not spend half of your talk "motivating" your topic.
Have a rhythm. Let's be honest
Tell a story.
Make sure you solve an actual problem.
Not everything you say has to be brand new.
Never let anyone touch your slides after you have last seen them.[..]/how-to-get-better-at-presenting-in.html

Don't darken the room
Don't use age-old clipart
Don't drone[..]6-mistakes-you-should-never-make-as.html

An average is better than an arbitrary point
A range is better than an average
A histogram is better than a range
A time series is better than a histogram

Instead, Abrahams suggests taking actions that make you present-oriented, because you can’t be worried about the future when you’re in the present. Do something physical, for example, like shaking out your arms. You could also listen to a song or playlist, count backward by sevens, or practice tongue twisters. -[..]anage-your-public-speaking-fears-anxiety
