Some advice-
1.) Keep your hand away from your mouth the audio is fine just if you are going to have a picture in picture of yourself be cognisant of your actions seeing someone talking while their mouth is blocked by their hand is distracting.
2.) Give us some actual analysis statements like I really like Ray or these two guys are good top and mid lanes does give us anything of value they are opinions. I know your video would be too long to get this in-depth every game but look at this article for a good analysis of a game NRG vs Immortals Breakdown.
3.) Try and eliminate some filler words when your talking. There are a lot of "you knows" "ums" and some others that provide now value and make it hard to listen to. I know its hard but just something to work on in upcoming vids.
4.) I know you said you were going to update some graphics and clean video up but you Power Rankings List desperately need an upgrade. The logo's coming in at as you announce the teams is nice but the crap list next to them is an eye sore. Just a thought not sure how hard it is but maybe a good idea to do is reveal one at a time as well. Start with 10 and as you talk about them have them pop up on the list leaving 9-1 in the power rankings a cliff hanger while you roll through them.
Hope these help!
Some debate now-
I want to know what is weighted on your power rankings. I feel you miss some things like TL have a jungle suspended, APEX unable to beat anyone who has looked good, and C9 looking great against teams you have ahead of them. Power ranking I tend to agree with are here- Power Rankings
