Thanks for the advice! Yeah, I'm considering focusing on my longer videos; however, most of my videos have copyrighted content. I actually don't think I'll meet the monetization requirements, haha.
I've created another channel for my self-made animations. I thought about uploading them to my current channel, but I think it might be a bad idea because the niches are so different. I've uploaded unrelated content to my channel before, and I could tell it affected the algorithm.
So, yeah, I'm building another channel from scratch, while keeping my current one for the motivation to practice guitar.
