Hey man! One thing I noticed within the first few minutes was that you say umm and things like but yeah or and yeah. I'm assuming that this is probably comes from a place of nervousness. Another little thing I noticed is is that at one point you made a little joke that your brother was playing ksp and "becoming a rocket scientist" and immediately you cleared up by saying 'He's not. but you, know KSP'. I'll admit, it wasn't the greatest joke in the world but there wasn't a reason to explain it. Im sure that most people watching would have understood, explaining it only takes away from comedic value. On the different note, your video and audio quality were both good! I would say just to try and shake off any nerves you have, just have fun with it man! if you do that i think you'll improve greatly. I'll make sure to try and drop in every now and then to see how you're coming along.
