Looking for adc mentor

Looking to get better with adc :). My main adc champs are kalista, draven, and ashe. Kalista is my best and favorite. Didnt love any champ enough to main them until she came out. Its hard to realize what every one of my mistakes are when im against another low elo player like me who doesnt know how to punish me for certain mistakes just like i dont them cause i dont recognize them. So theres a lot of mistakes hard for me to notice i make when i dont get punished for them, except for the rare times your against a smurf. I was hoping someone wouldnt mind helping me learn better :D. I like to use attack speed mark/quints on kalista it really works tons better for me then using AD ones since it helps her kite better plus you stack E more. On draven i use AD mark/quints. On ashe sometimes i use AS sometimes ill use AD. Once i get a new rune page im thinking of making a crit one for her.
