Nice to see this man! A few suggestions:
1: If possible, try to capture your Teamspeak view, there viewers will be able to see who you're talking to.
2: Your teamspeak sounds are way too loud, you can lower that down a bit in the Teamspeak settings.
3: Might be worth having some kind of footage in the background, remember that is YouTube, people expect pretty pictures :P
Otherwise, very nice stuff, can't wait to see more.
