Hi,
Just watched the replay from your view. I'm still on my laptop though since my PC is still in the shop
I spotted a ton of mistakes but I'll just list some of the bigget ones here. Overall you did pretty good considering you're not a Z player.
First off, you basically never scouted. Sure, you did here and there, but you never scouted where it would actually benefit you. Scouting is arguably the most important part of the game.. and something I need to work on as well.
You made defense without scouting him... I believe you made your first sunken at your natural once you spotted he had fast expanded. Making a creep colony is fine, but then you wasted another $50 morphing it into a sunken... if you had scouted, you'd know whether there was an imminent threat.. you really only need to morph once you know he has enough units to run you down.
You clumped all your overlords together. You continued to do this even after he attacked you with corsairs. Use those overlords to your advantage and keep the map covered. Don't worry about corsairs unless he really targets them down.
Spend your money. You had too much money at many points in the game. The Protoss player was really bad too, I saw him at over 2000 at one point!
All you needed to do for a much faster win was once you saw him fast expansion, just made hydra and try to take it down. If he defends too well, then you camp outside his base with lurkers, hydra, and overlords, and then mass expand the map. You opted for mutalisk which is okay, but after your initial attack you should still force him in with lurkers and hyrda outside his base. Instead, you stayed in your base the whole time.. Zerg always has to be on the attack, in every matchup.
Hope those tips help
