Honestly... you haven't learned public speaking. Watch any widely-acclaimed comedian and tell me there's any lack of dry wit and piercing insight. Those routines are speeches. Pick one that you like and dissect it to see how it works.

There's two giant components to public speaking: (1) not freezing up and (2) successfully communicating what you want to communicate. Well, really, those are the two components to any form of communication. For most people, this is circular: they freeze up because they don't think they can communicate, and they can't communicate because they freeze up: so learning public speaking is a matter of breaking that cycle on either end.

Your speeches are good if you got your message across. Sometimes that requires getting a laugh. Sometimes that requires a plot twist to make them reconsider. Sometimes that only requires reciting the facts without embellishment. It depends on your audience and your relation to them. A "master key" that doesn't recognize that you can't give the same speech to a group of 5 year olds that you gave to a group of Nobel laureates is useless.
