You have any tips about YouTube commentaries?

Hey, guys! I have started my youtube channel 3 months ago, and I have gotten a lot of great feedback! I am currently little bit over 500 subs, which I think is a lot in this short period. Not sure if this is normal? I would love to get feedback from you guys on how you think I am doing, and what I can do to improve as a player and a YouTuber. Would be awesome to get feedback!

Best Regards, Argus
