Silver 3 Looking to Improve

Alright so here is the deal, I have been playing with a team for a long time. Now I'm playing with two, I have been asked to handle some shot calling with the support. It's something I do alright, but I know I can improve at this and wish to get better. I love playing this game and getting to gold or even challenger would be awesome. But I want to get better, right now my jungle is a bit strange. is my best right now. With coming right behind him. I am alright at playing and a bit okay with playing . But I know I can get better, right now I can do both the ward Insec and Flash for him. I just feel like I am getting closer to getting better. I'm hoping for some help in any way that comes. I do use Curse Voice and Skype, I'm also using Replay.gg right now to watch my games. I main support and jungle. I would really like to improve past this and get better. Step by step I just want to get better and faster, so I'm looking for a team where I can learn to play better. I have a fairly deep champion pool and am willing to listen and learn to play again if need be.
