I'll link some channels. I personally think it's best to search for specific topics when you need them so I'm not going to send videos individually.
I would personally advise making sure you like the artists work before taking advice; make sure they're credible and that it fits with what you actually like. I say this because you are guaranteed to get conflicting advice and you're going to have to decide who to listen to at times. One of my biggest issues was that i wasn't using my own intuition enough so i would advise trying to make sure that you can understand WHY you're getting the advice you are and when it applies.
People call advice "rules" and i find it irritating because "learn the rules before you break them" just doesn't make logical sense to me- Its more "cause and effect" than an actual rule. Doing certain things is going to get different results, so be careful not to get stuck doing one specific thing. Sorry if that didn't make much sense, but to summarize be careful with how you listen to the advice.
Here's some art accounts that may be useful:

(also sorry if that came across as rude, i was attempting to be as clear as possible so it may come off as harsh; that wasn't my intention.)
