Need A Teacher PLEASE

Lately, i've realized how bad I am at League Of Legends and really want to get better. I play mostly Jungle and Bot, but I'm trying to learn mid lane. Champions I want to get better at in specific include: Katarina, Taric, Leblanc, and any top laner.

I'm in NA servers IGN: MrSkink Mains: Fiora, Malphite, (Hopefully Katarina) So, anybody willing to help me out would be much appreciated. Thank you![zombie-nunu-bummed]
