opening
ok im going to write this as i watch the replay the opening attack was nice you saw his opening build. If your observer had gone straight in and saw that the wall was weak I'd go straight to 8 gate and kill him. A super fast 3rd inbase to me if the wall is strong though(which it isnt atm but he may buff it up id expand again hes already commited 400 minerals for it y not you? you have obs for vission and im assuming your going to get blink or charge for anti drop. After this you did a 6 gate immortal push and busted his front. A good move.
Behind the push
I noticed your not fully saturated on either base (2 and a half lines on minerals) so thats something to improve. You also didnt macro at all behind the push when hes in his main like that id suggest taking a few seconds and either expanding or chronoing your gateways or dropping 2 forges and simply get more ahead. You then went and attacked up the ramp into his concave which was excatly what you shouldnt have done and lost more army than needed. I feel when medivacs are out without zealot to tank dnt attack up ramps at terran although thats just me. In fact re reading this just go to pure outmacro him when hes on 1 base theres more than 1 way to kill someone one of them is killing his base but sometimes thats risky as in this case. The second option is to starve him and get 3 minings bases going and overwhelm him when hes allowed to expand.
Staying too long
I still feel you couldve taken a 3rd behind that push easily. He had plus one the whole time over you too maybe try getting ouble forge behind if your don't want to expand eventually just poking forward and back loses you your advantage without any macro behind it. Why do you keep fighting him? just pull back and keep forcefielding his ramp if you want to although medivacs are out so maybe not. Make him come to you sentrys give you an amazing defencive advantage. Pull back and get sentrys and +1 1 and you have an easy win staying and fighting on low numbers with terran having better upgrades isnt what you want to do as im sure you now know since i wrote it 5 times.
putting yourself behind
So the disadvantage of putting down a lot of tech at once is you have less money to spend on bases/army. I also think if you that far ahead and killed a lot of workers go dts force his mules into scans. You also didnt deny the 3rd at all when you couldve sent 1 zealot and spread army outside his base.
The Battle
He hit with + 2 2 timing and because you delayed your forges/expand so long you didnt have either a) a **** load more economy so you could pump out way more units or b) upgrades over him.
Little things can make a big difference
Your saturation per base is horribly off too look at replay and how many probes per base on mineral lines. Yea i feal from here on he has the advantage and just doesnt let go of it. The dt snipe was good but i think sending them to different bases wouldve done more damage economically and scout wise wouldve given you more intel. That's a multitasking thing and you did snipe a base so cant complain too much. Didnt even scout his 4th with those dts you really want to scout everything and leave dts just to force scans so theres less mules everywhere and it gives you map awareness. I'd also say you don't take bases aggressivly enough having now seen you have no 4th and over saturated on your 3rd by heaps. remember its better to long distance mine once you the max income rate of 2 and a half lines of workers per mineral line per base as over saturating doesnt increase you income and long distane mining gives you some extra. Your 3 3 started when his finsihed. no cancel on 4th. never got blink to avoid clogging in the chokes vs terran if your stalkers are in the way and you dnt have colos blink your stalkers to the side which also reduces damage from emps so the your zealots can charge through still not a good idea when your upgrades are worse but helps.
My main thoughts on where to improve :-
Your macro behind your aggression needs work either upgrades or expand (get more ahead)
Your early attack decision was good but your stayed too long you tryed to just insta finish it be patient
You got a robo for obs so use them for more map awareness. aka don't let him state your 4th for free.
Worker saturation check it and start using it to your advantage
hope this helps sorry if it sounds mean i have a very critical view when i analyse replays cos they are generally mine
