Pretty good dude. Your aim is pretty decent, you mostly just have to work on your decision making and movement. You have a lot of avoidable deaths simply because you tend to walk in straight lines while shooting (e.g walking directly into a Zarya beam instead of strafing to dodge it) and not using line of sight effectively. I saw a lot of deaths because you ran away in a straight line rather than trying to lose line of sight or simply strafing to make yourself harder to hit. The biggest thing I noticed when I played on my 2nd account (placed 2400) is that headshotting people was incredibly easy because they walk in straight lines. I'd say it's more important to work on aim/movement than anything else, you'll climb faster doing so.
One thing I would say about your ults is that it's pretty important to shoot first before ulting. Don't make the mistake of getting a good flank and ruining it by simply pressing Q. I promise you'll get a lot more big 4-5 man ults if you get 1-2 people low with 3-4 shots before pressing Q. Other than that just try to play with your team more instead of constantly frontlining and trying to get picks. E.g your Mercy on Dorado was getting destroyed by Reaper and nobody seemed to want to help, but you were clearly able to out aim that guy so if nobody else wants to defend your Mercy you should do it instead. On Dorado last point it mostly comes down to either a big push from the attackers, or a pick from the attackers and follow up push. You being in the frontline and getting a pick then dying on defense doesn't actually help very much, keeping your Mercy alive is a lot more important. Although stuff like that you'll just pick up as you get better.

Thanks for posting the vids Buzz, I made a lot of mistakes too.
I feel my positioning and wasting ulti's are the worst and not actually my aim. As H2Scott said it the deciding making for me that needs to improve. I only bought the game a few weeks ago so lots yo learn.
Good points from Scott I was the mercy getting destroyed.!!
Btw your welcome to join if you need a group? What is your Battletag?
My other account is 3000 now. I was getting like 60-70 points per game for some reason.

Try lots of heroes out rather than sticking to a few specific ones. Also good to try all the different roles as well.
