Master Yi gameplay I need advice on how to improve with Master Yi even more!?!?

Hello, I have some recordings of me player Master Yi on my stream, and I am obviously trying to improve, and I think the best way of improving is taking input from other players! so I am here to ask what your thoughts of me and my knowledge of Master Yi level is at. What should I work on? what am I missing in my builds? what should I be doing more often? I'm basically wondering questions based around how I can improve in LoL with specifically Master Yi for now.

Here are some more videos that I think you will find beneficial for evaluating me! Thanks! (https://www.youtube.com/watch?v=ZsYKLBDr60I)
