Bronze Support Looking for Coaching :D

Hi, my name is Exerxes, and I am a Bronze Support main. I play Sona, Thresh, Soraka, and Zyra Support. Sona being the one I am most comfortable with and Thresh being the one I enjoy playing the most. I'm looking for someone who is willing to help me get better at league through coaching or Analyzing my Game play. Below I have a Spectator mode view of one of my most recent games as Thresh. This is a game I am particularly proud of which makes it the perfect candidate for coaching. I encourage you to watch the video prior to contacting me so that way you know what you have to work with.

Thanks and I look forward to working with you!

My personal notes on what could be improved:

• More vision. I barely used any wards.
• 7:20 I killed my adc... but I tried to make up for it ._ .
• I overextend too often. gotta stay with the group :P
