Is this a good way to end a Let's Play video?

Words are important when you want to use. Have you ever seen how sales people talk? They know the technique to trap customer. I am not saying you sell something just giving you points.
O.K. I will talk about what you have said.

"And that's it for today, if you really enjoyed the video, go ahead and leave me a like and comment down below also don't forget to hit that subscribe button, you won't regret it! Thanks for watching! "

You have used IF YOU REALLY ENJOYED THE VIDEO. Mean those who have enjoyed may think it was not good. Do not talk negative. Then you talked GO AHEAD AND LEAVE ME A LIKE AND COMMENTS DOWN BELOW. When we are watching video we do not got such time to listen all this make it short.
Finally YOU WON'T REGRET. This is not good. How do you know viewer will regret or not. You are talking negative. But some time we got to use negative such as, I want you to open a box. I will not say Open the box rather I will use do not forget to open the box. It is psychological when we say do not do, we want to do right?

Example:
(Song slowly fades in) Thank you for watching.(say politely with smiling face)
Do not forget to subscribe (say quickly)
and...like (add your text).
(Beat drops in those after-video menus that show previous video and subscribe button with other social media links)

Hope you do not mind my honest comments.
