I made it through 2 minutes. Tony, you started out with good energy, but then, um, you just, um, lost me, um, when you, um, said, um, Ben, Johnson, um, instead of, um, Niko Medved.
A word of advice.
Script out what you want to say and, at minimum, have specific bullet points to speak on.
Record your presentation more than once.
Edit the final presentation.
You can download a software tool like Camtasia (costs about $400, but it's a great investment for what you are trying to do) and add your screenshots, as well as multiple layers of animation to enhance your presentation.
Clean up the errors and then present your video. Do that and I will make it past the 2 minute mark.
You want to be professional with this, so invest in production and editing. You have the passion, you just need the polish.
