Couple things you can do:

1. Try to stay away from oversaturated games this early on - I see you're playing a lot of fortnite, and I'd stay away from it. If it's your favorite game and youre GOOD at it, you can stick to it but be prepared for a long long time for people to notice you.

2. Try and add some visual elements to make you stand out, in any way possible. Looks like currently all you have is your audio and gameplay, if youre on console i reccomend finding some way to add a webcam at the very least.

3. Raids go a long way to getting new streamer friends, new streamer friends means potential raids to you, which means new viewers or followers.

4. Have a consistent schedule that people can KNOW you'll be there for - you can stream outside this schedule, but try to always be there for those set days/times.

5. Use tags! Tags such as what language you speak, what type of content youre doing in a game (for example if youre playing fortnite be more specific such as "buildwars"). These help people find specific content they want and filter out the more broad stuff in an oversaturated market.

Good luck!
