Looking for a serious ranked team

Hi I'm currently an S4 mid laner looking for a serious ranked team. I want to improve my play and gain experience with an actual team that is serious about improving and climbing into a higher elo. I accept criticism well and adapt very fast whenever I get new info. I'm really starting to take this game seriously and want others who do as well to help improve my play and also gain experience as a full team in high pressured moments
