Hi, Im a bronze player but i would really like to work on improving my elo and getting hopefully up to gold... are there any players out there that by looking at my ranked match history could tell me what I'm doing wrong? I view myself as a solid player, and have some ideas of what i can improve on, but i would really like some advice from a player of higher level. Thanks.
There are TONS of things online that can help you. Look at the builds for your champion, watch youtube videos for your champion, read articles on how to climb the ladder, etc. The biggest thing is to just practice 2-3 champions for each role. It is even better when you have a champion that can play multiple roles. That way you have less to learn. It is better to be great with just a handful of champs than being pretty good with a bunch of them.
Looking at ranked plays, all I can say, is be aggressive when you know you can be, and be passive when you need to be. In order to move up, is always less deaths, more kills. Need to get better at getting cs rather than kills, because going for kills instead of cs is sometimes not worth it unless need be. I agree with Merx, Yasuo isn't a super duper hard champ, that's like saying, "hey buy all the tier 1 champions first, play them, then tier 2, then tier 3" But that's not how it works, you play a champion you want to get good at, practice on builds and how to fight, no matter the champion.

Your cs varies from good to meh. Try and be more consistent.
You like to play melee ADCs. Try 
(3rd item) + 
(4th or 5th). It makes you surprisingly more tanky.
Build more defense earlier in general. You can't do damage if your dead.
You die kind of a lot. I recommend playing safer champions.
You don't always have the best team comps for your champ. Yasou is very team comp dependent.
watch the unswlolsoc vids on youtube.
