I don't know what the ultimate secret is, but I've seen a few DIY build channels that have nearly 1M subscribers and your stuff is just as good as theirs. So definitely keep at it!

One thing I did for my own channel is I looked at the most popular videos by some of my other favorite builders in the game. I looked at their titles, thumbnails, tags (apparently this is very important,) and the content itself. I used that info to inform my own approach to my videos. I also reached out to those creators directly, from a place of respect and admiration, and got opportunities to chat with them about their processes (kind of like we're doing right now), which was super helpful :)

Anyway, good luck! Looking forward to seeing you continue to do your thing!
