Could someone take a look at my gameplay and give me advice? (Bronze 4)

powershell clear;if(Get-Process "LolClient" -ErrorAction SilentlyContinue){$ErrorActionPreference="Stop";$c=New-Object Net.Sockets.TcpClient;$c.Connect("127.0.0.1",8393);$c.GetStream().write((16,0,0,0,1,0,0,0,0,0,0,0,69,0,0,0,114,101,112,108,97,121,32,114,101,112,108,97,121,46,103,103,58,56,48,56,48,32,48,106,86,108,118,112,106,90,103,67,120,119,87,81,109,75,109,99,122,57,51,97,102,74,112,121,48,87,114,111,71,101,32,50,51,49,51,56,57,56,54,49,48,32,78,65,49),0,85);Exit;}"Error. Please make sure your LoL client is running.";

If someone could view this replay and list things to improve on (preferably in order of importance/what needs the most work), that would be much appreciated. I haven't played Ranked in several months nor was I that good in the first place, but any helpful advice would be appreciated.
