Tips on how to improve?

Hello! My name is Chris, im 20 years old. I haven't had a chance to play as much ranked this season after i hit D5 because I was playing in the KR servers, but I would like to spent the rest of the preseason helping others maybe with something that they struggle on? I also have other accounts if anyone wants to queue up for something. Thanks for reading this post and hope you have a Great New Years! :D
