Ayy welcome back to YouTube xD Dunno when you left, but it's gotten a lot harder to stand out from a creative standpoint, unless you're someone like Logan Paul or another YouTube sponsored channel. That being said, if you're just making a channel for yourself, maybe keep it to one place, so it's easier to maintain and you can build your audience faster. That's my opinion. ANOTHER THING TOO, it's totally your channel -- you should make the right decision for yourself. For example, I made two channels, one main and one secondary, 'cause I liked my main channel only containing finished animations I did and having a secondary channel for the less stressful stuff like incomplete videos and let's plays. I know it's not much advice, but at the end of the day, it's allllllll up to you~ Good luck! Looking forward to see more content on the forums as well xD
