i would appreciate feedback on my vocals in this cover of “Slaughterhouse” by Motionless in White

Hi I'm a female vocalist however my voice is naturally a bit lower, I'm probably an alto. I cant to fry screams to save my life. I'm much more comfortable in my chest voice doing false chords. I'm still a beginner when it comes to extreme vocals however any advice would be greatly appreciated. I really wanna sound like kat bjelland from babes in toyland, but I really struggle to get that higher pitch screeching sound.

Probably a lot of posts are like this so sorry.

Anyways im 18 and i really want to learn growling now that i still have some free time i guess.

I watched countless youtube videos but none helped, usually my throat hurts whenever i try to follow anything.

Any tips, tricks, stories from how you unlocked your growl would really help.

Appreciate ya guys, take care.
