Feedback on my rap

I'm still slayin and killin
Watch other rappers blood spillin

My rhymes lift you from down under
Finished instantly one hit wonder
Faster than thunder

Like a instant death battle
Your rhymes sound worse than a brattle
My name makes your heart rattle

You're raps make people want Midol
Mine make me peoples idol

It's like a tidal wave
You better run for that cave
This music is for no rave

You're rhymes are weak
My rhymes leave you bleak
Leave you lost in losers creek
No wonder why people call you a freak

People want me to get clean
Go green
I would rather end up worse than Charlie sheen

It's almost time to finish you off now
I'm on fire time for the blast off plow
You curl up like a cat did you just say meow

You take me for a joke that’s the last straw
I'll leave you with nothing to gnaw
Time to freeze you will never thaw
Strap you down with this chain saw
You're finished off left with a broken jaw
This is my law

I show no compassion
Like having a straight face while you're head split open/and it mashin

Bashin blood
Flash flood

Fix dead locks
Break your face in 3 spots
Have you end up worse than 10 mace shots
Have the most evil plots

They call me Legendary
My rhymes are very scary
At night you better be very wary

Stop buggin me
Go stay high on trees
I hope you O.D.

My rhymes come like shipments
Make you look like misfits
Now you're really on my hit list

I cause nightmares
Last 10thousand light-years
You're worst fear

Here comes the almighty
Better get your ears tidy
Not a time to be flighty
Don’t you dare call me whitey

Crack you're brain
Step up and you get slain
You're rhyme basicly come drained

My rhymes are stright up raw
Leaves you in awe
All I hear from you is blah blah blah
You scratch like a cats claw
This is over you're just a huge flaw

You sold your soul for some pride
Yet you still run and hide
Your whole rap life is a lie
You don’t wanna see me on this beef side

You need to watch what you say to me
Don’t run and flee
Trying to be low key
You're finished that’s my fee

Try multi syllable rhyming and internal rhymes.

Then after that move on to applying wordplay.

somethings missing cant put my finger on it but maybe i'm imagining things
