The only thing I've seen recently different than what you're doing is that the videos my wife is getting served currently with AI voiceover have moved on from the Minecraft/random game background, and are currently serving various (usually AI also) images as the background. I'm not sure if you want to look into following that trend. I'll find an example...

I'm not sure how easy/hard that is to replicate, but it may boost follower ratio so I thought I'd mention it. tiktok metadata:Y29qb3ZpfDczMzMyNDEzMTM2OTA3MzM4NjYgVGhlc2UgVmVnZ2llIFdhcnMgZm9sbG93IHRoZSBjdXJyZW50IHRyZW5kIEkndmUgYmVlbiBzZWVpbmcuIEknbSBub3Qgc3VyZSBob3cgZWFzeS9oYXJkIHRoYXQgaXMgdG8gcmVwbGljYXRlLCBidXQgaXQgbWF5IGJvb3N0IGZvbGxvd2VyIHJhdGlvIHNvIEkgdGhvdWdodCBJJ2QgbWVudGlvbiBpdC4= ~~~
That's actually pretty sick. It's just the right amount of weird.
I actually saw one of these channels, and it was basically the same, but it was about the Roman's and Visigoths, but they were steampunk and space travelers. It's fairly cool, to be honest.
Currently, my videos are 2/3 gameplay and 1/3 a static sci-fi image, but with the blender stuff, I'll have static city footage with some moving images. Using AI to get some stuff like that, though, could be worth looking into, too.
