First off, do not follow Trends too often that's going to basically kill your account if you ever decide to take a break.
Second, to make small art tutorials such as drawing an eye or how to draw hands.
Third, pick a demographic. Take your time thinking about who you want to be watching your content not just are the artist, but what type of people? Your art style may attract some BL manga lovers ( although I wouldn't really recommend it-) but you could also go for drawing popular k-pop members as well.
4th do not do "the follow for part 2 thing" it's rare for that for artist who aren't making a series such as a mini drama on tiktok there's only going to be a small number of people willing to watch a part two of a speed paint. As someone who constantly watched Tick Tock that was the most annoying thing possible it's always the part too or follow for part two etc etc it was annoying.
5th if you are going to follow Trends use popular audio clips that relate your content
6th expect your views to dwindle over time and then randomly Spike up that's how the algorithm is you get one popular video and then the next maybe get a few hundred views but it's still watched you got to expect that to happen don't blame yourself though
