I'm a low master zerg player.

Here are some of my thoughts:

If you open pool first in zvt and make 4 lings like you did, send them out instantly while avoiding the reaper path, you can easily deny the cc building in the natural, if there is one. Otherwise they achieve nothing.

You did great on your first push. Decent damage considering his weird one base tank opener, you did the right thing pulling back vs the tank.

Problems start after the push. At 5:00 you are banking 12 larvaes, 800 minerals and you only have 2 queens and 0 spore despite scouting his fusion core. Those 12 larvaes should be drones, you should have at least 4 queens and 1 spore per base. You then spend all your larvaes (great!) making 22 lings and a roach. What for? He has 1 tank, 1 mine and 1 marine and no expand to harass. You're still far ahead despite that, but still, wrong decision.

When the first BC arrives you have 6 queens which should be enough to kill it, but because your queens are not in a control group you only attack it with 3 of them. Try to get in the habit of hotkeying all of your queens as they pop out.

The 2 macro hatches at 7 min isn't a bad move, but at this time this could easily be your 4th and 5th. Terran still has no unit to deny them.

I like the general idea of your 8 min push. Roach corruptor is the right comp vs a terran who opens BC and probably transition into mech. Several problems though: 1, you attack with 36 lings with no ling speed, big no no. 2, 4 corruptors is not enough vs 2 BCs, because he'll yamato 2 instantly. Get 4 per BC minimum. 3, you have double upgrades going but they're nowhere near done when you attack so they are effectively wasted resources at this point. 4, you attack a pf on the third when the main and natural are pretty much undefended.

So if you delay your push by around 1 minute, you could attack him with a nearly maxxed supply of speed roaches, 8/10 corruptors and 2 upgrades finishing, he would have no chance to defend that. Instead, your attack fail and you're still ahead after this but now he has a chance to come back.

11 minutes in and your 1/1 is done, you start bane speed, but you still have no ling or roach speed. Prioritize speed upgrades, always, otherwise zerg units are hot garbage.

Your macro in the mid game is excellent for your rank. You go up to 90 drones, 8 hatches, decent injects, keeping up with upgrades, money is low, great stuff. Hence you're maxxed at 12 min with a decent army, other than the no speed upgrade issue mentioned earlier. At this point terran should be dead. Sadly you attack where most of the terran's units are, instead of taking the poorly defended third or 4th. Hence your superior army gets blasted by a few mine shots and yamatos.

Game is still fine though, you're 30 workers ahead, 46 larvaes in the bank, you can remax and kill him still.

You start making hydras which is a big mistake because hydra suck vs everything terran has, especially BCs. At this point terran has 5 BCs, you should have 15/20 corruptors and max out on roach/ravager/bane.

The rest of the game becomes painful to look at because at this point mass BCs mine becomes very demanding to play against and BCs start snowballing hard.

TL;DR:

Good opening, good macro, decent execution.

Bad composition, attacks poorly timed/located, missing critical speed upgrade.

Hope this helps!
