To join a team and improve my skills in Minecraft

I have been playing Minecraft for over 7 years and I have played bed wars for around a 2 years. I am always trying to improve and get better e.g. bridging.
I know rather a lot about the game and I enjoy it deeply. I may only be 13 but at least I am trying. I do also stream Minecraft on Twitch, I hope I join a team :).
