Here is a good example of how you could finish off your talk:
I've talked to you about the TV programme - Westenders, how it started and what the viewing figures are. I've also talked about why I think it so popular and how important the social issues are. Catch the next episode to find out more.
These are some examples of things you should avoid saying:
I hope you all enjoyed it. Don't you think I deserve a clap?
That’s the end of my talk. But I'd just like to add one or two things that I forgot to mention before.
I think I've bored you enough, so I'll call it a day.
Um, well, I think that's about it really. I can't think of any more to say...
