What am I doing wrong???

Nagasis - Summoner Stats - League of Legends
Nagasis / Bronze 3 0LP / 3W 11L Win Ratio 21% / Renekton - 0W 6L Win Ratio 0%, Jhin - 1W 4L Win Ratio 20%, Maokai - 2W 1L Win Ratio 67%, Leona - 0W 2L Win Ratio 0%, Lulu - 0W 1L Win Ratio 0%
Guys I need help! I'm not the best player at league and i can admit it. Its a team game and generally the only consistent factor is me. Leveling my account to 30 i felt like i did well enough most times and got a good grasp of Renekton. Seeing as hes a strong champ right now I felt like i could take him into ranked and see some even success. I had a 60% win rate with him in normals and while I didn't think I'd have repeat success in ranked I didn't think I'd be this bad. Can anyone take a look at my op.gg and give me some constructive criticism? I don't care how harsh it has to be! I'm 1/9 in my last 10 games and i just want to improve. I "feel" like I should be at least silver but my play isn't reflecting. Thanks for any input.
