How can I train my voice so I can sing like Axl Rose ?

I am 12 years old and my voice is changing constantly.
I like how Axl sings and want to know how I can sing like him. Stuff like "Nightrain" etc. Where he sings really high / screamy

Don't hurt your voice early in the morning, warm it up. Practice karaoke style, but turn the stereo down so you can hear your own voice.

Remember that you can hit the note with your throat, but you won't be able to hold it and change it until you can control your diaphragm. Axle could never finish even one song if he just sang the whole thing with his throat.

Unfortunately, the ability to hit high notes may not be up to you. You have a pre-determined range based on your physicality, but you can still be amazing within that range.

Call a person that gives singing lessons.

Voice classes, it sounds weird but you really do have to excercise your vocal cords.

eat some nails

if you want to sing high you get castrated (if your a boy) I DON"T SUGGEST THIS!!! this is where you lose your manliness and become a male soprano(highest vocal range)

you need to relize your voice is going to go down deeper so there isn't a way for you to distort your voice.

Scream and holler all the time.

Always be late to everything and hate everyone.

Then you are Axl Rose, if this was me I would rather be like Slash.. He has had long jevity.. Where is Axl??
