LF a mentor

Hi I'm Orkrist. I was wondering if someone in a higher tier, preferably around gold or above, could take the time to spectate some of my games and help me out a little. I really want to learn more about the game and improve my gameplay. I mainly play mid lane or top lane if I can get them. I can also play other roles but I'm not as good. My main champions are Zed, Riven, and Lee Sin. I would really appreciate it if someone would consider taking the time to help me improve. If you're interested just send me a friend request or tell me your ign. Thanks
