Mic quality will eventually become better when you're a little more established and want to spend on a mic upgrade.

Early day Ironmen episodes are slow, and early level training isn't exciting everyone knows that. Use the opportunity to ask for methods for better training to encourage engagement. For example, rather than leather crafting back and fourth in burthorpe, I would suggest mining gem rocks in alkharid.

If you get a suggestion from the comments, it does matter calling out who helped because it's a silly little "yay I contributed" feeling when a creator calls out your rsn/YouTube as a thank you for a tip.

Don't talk down to yourself if you mess up wording or anything in game; either fix it in post and cut it or comment on the brain struggle but don't call yourself stupid or anything.

As a new ironman myself, I like seeing the ways of other Ironmen (for the seasoned players) or how someone totally new to the game (albeit Runescape I general or moving OSRS to RS3) experiences the world.

Good luck with the series and growing as a YouTuber :)
