What Is A Good Way to Give A Presentation?

Hey, guys! Today, I gave a presentation on a book called "Next Society" in front of 20-ish people at our seminar.

I quoted a lot of information including statistics of Japan and the U.S., using visual aides such as graphs, and they joined discussion quite actively. But I still found it hard to make a good presentation because it was the first time... What do you think is a good way?
