For quick ult charge, I usually bully their tanks. Sometimes if a mercy is pocketing the tank I'll just let the mercy live to get ult charge even more haha then kill the mercy and then the tank.
Don't stick a tank that you or your team can't kill, it's actually bad because you feed the enemy healers loads of ult charge. Bait out hog's take a breather, and orissa's fortify before sticking them.
The recall after the pulse was completely unneeded. Your tracking is a bit off. Aim for the neck instead of the head, more bullets will connect and it will do more overall damage.
Could work on your blinks as you were blinking in walls and you aren’t zoning enough. A McCree could quickly headshot you considering you stayed in the same area for a long time. Always keep moving, especially as a 150 hp tracer
Honestly not bad for your first day. Blink management is key, I saw some not so well timed ones and other points where you were not moving so much, easy target. And really just spend some more time with her. And like people have been saying aim for headshots.
U dont need to recall everytime u ult, just blink away, recall is essencial and should be use in cases of near death or stall most of the times, but ye with some ult situations the recall is the safeste way to get back to ur team
Melee more. You could've meleed mercy there and have bigger awareness with your blinks. Get some tracing skills (aimtracing) go in backlines. Aim for their head. Yeah
