i am desperate for some advice on this TvZ replay

so i am realy trying to go for masters with terran this season and doing quite well against terran and protoss but bio/hellbat/thor vs muta/bling sometimes feels impossible to win. Since i am still somewhat new to terran i am looking for advice on my opening and if i got my 3 base production set up right. Anything else that might help me get better is greatly appreciated aswell of course :). Obviously i tried other ways to play bio in TvZ like bio mine or pure bio. Bio mine just feels very week and dependant on the widow mine hits but it might be the case that i just didnt give it enough of a chance. Pure bio would be a possibility for me but i dont realy know how to approach this and if i have the micro/macro to pull it off.
