How do I promote my mini web series thing?

Hello. To start this off, I’m a VERY smal YouTuber. I have about 100 subs. What I’m asking is how do I promote an indie project that I’m making mostly on my own with a concept I’m yet to see on the internet?

I want to use a mix of traditional art (I can’t do digital art to save my life TwT) and a bit of stop motion animation using paper. It is titled “Sleepy Fall”. It’s about a child (aged 4-7) who finds their way into another world, a crack in the fabric of what’s real and what’s not. There are 9 stages of this world, with a colorful cast of different entities. Some are nicer than others. The goal of the main character is to complete tasks for these entities in return for something (food, water, a map, directions, tips, etc). While they do this, they are desperately trying to remember things. They can’t remember their nam, their gender is unclear, and they have prosopagnosia, a mental condition where they can’t recognize faces. They are trying to remember their parents, memories, and friends, but can’t, both because they can’t recognize faces and the effects of this world can slowly chip away at one’s sanity. Also there’s just a cat that follows them around. Idk why I decided to add that.

My problem is that I don’t know how to get Sleepy Fall out there or promote it. It’s an odd concept, but I think I can do it. Any advice?

(Also, I plan for there to be 9 episodes total. Episode 1 should be finished in February-March, April at the latest. I’m still in need of voice actors >_<)
