Just checked out both of your channels. There's no point in joining a network at your size.
This being said, there are a tonne of networks that will accept you at this size. I know fullscreen will pull in anyone. Though, don't let them fool you. They are NOT there to help.
When they enchant you by saying "We'll help you grow!" that usually means that they're going to give you access to apps so you can help yourself and even then, they're not that great.
I was with Fullscreen for 2 years. In that time, they did not help me a single bit to grow my channel. I never spoke to a real person on that network until I requested to leave this year. And they wanted to enchant me to stay.
Learn these things, and you'll never need a network. Learn what falls under fair use. Learn how to promote yourself. Make evergreen content. With these tips, you'll undoubtedly do better with or without a network.
Don't join a network. You will literally earn pennies. Just wait and grow.
