oh a bronze zerg.
just focus on getting an expansion and keep consistent queen injections on your hatches, avoid 6 pooling or all ins to help you get used to applying early pressure but providing consistent re-enforcements.
so you macro you base, expand , build an army attack either their wall off or their expansion retreat before losing your units but not so far they're basically at your base, constantly build more units and once you feel comfortable or even trial and error just keep forcing pressure on them and don't forget to tech up.
easy wins can be from fast muta rush but leaves you open in ZvZ for mass speedlings / baneling attacks.
or i'll find the build tomorrow. i was a plat protoss player, changed to zerg ended up in silver i'm now top 8 platnium after using the build and adjusting it to my style. same could happen for you.
but in bronze it's not a whole lot of meta game you end up with early - mid game rarely does it ever make it to a medium - end game bronze is cheesy and all in. once you get you're base macro down and a consistent supply of units you'll end up gold then the game changes and becomes really interesting. after gold league it's when it becomes fun and mistakes are costly.
