I come across as amateurish? Maybe that's because that's what I am! I know I come across as real, which is my main goal. I also think you're being overly critical, and your speech classes and schooling make presentation flaws stand out to you more than they do average people. That probably wasn't my best video either, as I was trying to find the words to explain a complex topic in the simplest way possible.
I am willing to take constructive criticism. I know my presentation isn't perfect. I've literally sought out advice. But I don't care to hear from someone who immediately insults me about a "big ego" when they don't understand anything about how this forum works or some of the personal dynamics in here because they're brand new. Nah man, when you say something like that after trying to give me feedback, then you sound like you have an agenda, not like you're trying to help. So I don't care to listen at that point.
